Release Notes

time-rs/time (time)

v0.3.55

Compare Source

Fixed
  • Avoid underflow in DateIter::nth, ensuring correct behavior.
  • Avoid overflow when deserializing timestamps.
  • Handle out-of-bounds data when deserializing.
  • Don't assume that the format being deserialized was generated by the serializer; this previously
    led to some valid values being parsed incorrectly and others being rejected.
  • No longer silence errors when deserializing UtcOffset.
  • OffsetDateTime::from_unix_timestamp_nanos and UtcDateTime::from_unix_timestamp_nanos correctly
    return None for all out-of-range values, rather than unexpectedly panicking in some situations.
  • OffsetDateTime::checked_to_offset and UtcDateTime::checked_to_offset correctly return None
    for all out-of-range values, rather than unexpectedly panicking in some situations.

v0.3.54

Compare Source

Added
  • PrimitiveDateTime has been renamed to PlainDateTime.
  • Duration has been renamed to SignedDuration.
  • Iteration is now possible over Date, Month, and Weekday. Relevant iterator methods have been
    overridden to ensure maximum performance.

For both PlainDateTime and SignedDuration, a non-deprecated type alias has been added for
backwards compatibility. The new names should be preferred.

Changed
  • The associated metadata type (for powerfmt implementations) for various types has been changed
    to () and made public. This guarantees that no additional metadata will be present.
Performance
  • More gains when parsing RFC 2822.

v0.3.53

Compare Source

There are no publicly-facing changes in this release. It solely works around the cookie crate
relying on an implementation detail of time that was never part of the public API (and thus
subject to semver guarantees). The internal API has been reverted to the extent necessary for
cookie to compile. This measure is temporary; the internal change will be re-applied in an
yet-to-be-determined future release.

v0.3.52

Compare Source

Fixed
  • Subsecond values in the time! macro are parsed using the textual representation, ensuring
    accuracy. Previously, they were parsed using the floating point representation, which could result
    in a loss of precision and even invalid values.
  • The date! macro could previously create an invalid value that would then panic at compile time.
    The macro now emits a proper error instead.
  • When parsing an invalid format description, an edge case would inadvertently panic. This now
    returns an error as intended.
Added
  • Support default values when parsing

v0.3.51

Compare Source

Fixed
  • time compiles with macros enabled. This version is otherwise identical to v0.3.50.

v0.3.50

Compare Source

Fixed
  • time compiles with macros enabled. This version is otherwise identical to v0.3.50.

v0.3.49

Compare Source

Fixed
  • Due to a long-standing bug in the Rust compiler, v0.3.48 caused a number of crates to stop
    compiling. A patch has been added that avoids triggering the bug.

v0.3.48

Compare Source

Security
  • The number of digits parsed by [subsecond digits:1+] is capped at 32 to avoid parsing unbounded
    user input. Digits after the 9th have no semantic meaning.
  • Explicitly specify #[repr] for Weekday. The value of the variants is relied upon in multiple
    locations for soundness. The practical effect of this change is nothing, as Rust has always mapped
    C-like enums to 0..N in memory.
Compatibility
  • Non-UTF-8 formatting and parsing is deprecated without replacement. It is recommended to only
    format and parse valid UTF-8.
  • format_description::parse is deprecated. It is recommended to use
    format_description::parse_borrowed::<3> or format_description::parse_owned::<3>.
Added
  • All types in the unit module have a generic parameter, though this is currently not used for
    much. Usage will be expanded in the future.
  • Comparisons between types in the unit module and the generic Unit type are permitted.
  • Support for rand 0.10
  • Version 3 format descriptions
    • Only UTF-8 is supported. As a side effect of this, [ignore] requires that the remaining input
      not begin mid-codepoint.
    • Representation is deliberately opaque to allow for arbitrary changes going forward.
    • format:false is supported on [optional] components. This is not possible in version 1 and
      version 2 format descriptions due to API compatibility.
    • The time::serde::format_description! macro uses a new, clearer syntax for version 3.
      • time::serde::format_description!(mod foo [Date] = "[year]-[month]-[day]");
      • Unlike version 1 and version 2 format descriptions, the type is not automatically brought into
        scope. You must import it yourself.
    • Nonsensical combinations of modifiers are rejected. For example, you cannot specify
      case-sensitivity when parsing a numerical month.
    • [year] defaults to range:standard
    • Components and modifiers are case sensitive (and always lowercase).
Changed
  • The convert module has been renamed to unit.
Fixed
  • Macro hygiene has been improved by specifying re-exports.
  • Fix handling of T in ISO 8601
  • Support parsing the full range of UTC offset hours
  • Version 1 nested format descriptions may now start with a component. Previously, a lexer bug
    unintentionally prohibited this.
  • Error when ISO week date overflows the max year. This would previously panic.
  • Error when padding is specified in strftime format descriptions but the component is not. This
    would previously panic.
Performance

Huge performance gains across multiple areas, including:

  • optimizing equality checks for Duration
  • optimizing Display impls for all major types
  • optimizing the formatting of components and well-known formats
  • precomputing metadata when formatting, reducing allocations
  • adding fast path for typical RFC 2822 usage
  • optimizing strftime parsing
  • refactoring format description parsing

Depending on the area, gains range from 3× to even 11×.

v0.3.47

Compare Source

Security
  • The possibility of a stack exhaustion denial of service attack when parsing RFC 2822 has been
    eliminated. Previously, it was possible to craft input that would cause unbounded recursion. Now,
    the depth of the recursion is tracked, causing an error to be returned if it exceeds a reasonable
    limit.

    This attack vector requires parsing user-provided input, with any type, using the RFC 2822 format.

Compatibility
  • Attempting to format a value with a well-known format (i.e. RFC 3339, RFC 2822, or ISO 8601) will
    error at compile time if the type being formatted does not provide sufficient information. This
    would previously fail at runtime. Similarly, attempting to format a value with ISO 8601 that is
    only configured for parsing (i.e. Iso8601::PARSING) will error at compile time.
Added
  • Builder methods for format description modifiers, eliminating the need for verbose initialization
    when done manually.
  • date!(2026-W01-2) is now supported. Previously, a space was required between W and 01.
  • [end] now has a trailing_input modifier which can either be prohibit (the default) or
    discard. When it is discard, all remaining input is ignored. Note that if there are components
    after [end], they will still attempt to be parsed, likely resulting in an error.
Changed
  • More performance gains when parsing.
Fixed
  • If manually formatting a value, the number of bytes written was one short for some components.
    This has been fixed such that the number of bytes written is always correct.
  • The possibility of integer overflow when parsing an owned format description has been effectively
    eliminated. This would previously wrap when overflow checks were disabled. Instead of storing the
    depth as u8, it is stored as u32. This would require multiple gigabytes of nested input to
    overflow, at which point we've got other problems and trivial mitigations are available by
    downstream users.

v0.3.46

Compare Source

Added
  • All possible panics are now documented for the relevant methods.

  • The need to use #[serde(default)] when using custom serde formats is documented. This applies
    only when deserializing an Option<T>.

  • Duration::nanoseconds_i128 has been made public, mirroring
    std::time::Duration::from_nanos_u128.

  • Various methods for truncating components have been added, avoiding the need to call the fallible
    replace methods multiple times.

    For PrimitiveDateTime, UtcDateTime, and OffsetDateTime:

    • truncate_to_day

    For Time, PrimitiveDateTime, UtcDateTime, and OffsetDateTime:

    • truncate_to_hour
    • truncate_to_minute
    • truncate_to_second
    • truncate_to_millisecond
    • truncate_to_microsecond
Changed
  • The minimum supported Rust version is now 1.88.0.
  • Significant performance gains in numerous locations. No public APIs were changed or removed as
    part of this.
  • The size of error::ComponentRange, along with types that contain it, has been significantly
    reduced.
Fixed
  • The PartialOrd and Ord implementations of UtcOffset now return the expected result.

v0.3.45

Compare Source

Added
  • time::format_description::StaticFormatDescription type alias for &'static [BorrowedFormatItem<'static>]. This is the type returned by the
    time::macros::format_description! macro.
Changed
  • The minimum supported Rust version is now 1.83.0.
  • All floating point methods on Duration are now const fn.
  • All setters on Parsed are now const fn.
  • The serde dependency has been replaced with serde_core, This reduces compile times by not
    including unused parts of serde.
  • Date::from_julian_day uses a new algorithm, resulting in an approximately 16% performance
    improvement. This method is used internally by numerous other methods.
  • util::is_leap_year uses a new algorithm, resulting in an approximately 8% performance
    improvement.

v0.3.44

Compare Source

Fixed
  • Comparisons of PrimitiveDateTime, UtcDateTime, and OffsetDateTime with differing signs (i.e.
    one negative and one positive year) would return the inverse result of what was expected. This was
    introduced in v0.3.42 and has been fixed.
  • Type inference would fail due to feature unification when wasm-bindgen enabled serde_json.
    This has been fixed by explicitly specifying the type in the relevant locations.

v0.3.43

Compare Source

Added
  • Support for rand 0.9
Fixed
  • In the convert module, any use of per with types that were not the same (such as
    Nanosecond::per(Second)) would not compile due to a bug. This has been fixed.

v0.3.42

Compare Source

Added
  • Time::duration_until
  • Time::duration_since
  • per_t method for all types in time::convert. This is similar to the existing per method, but
    can return any of the primitive numeric types that can represent the result. This will cut down on
    as casts while ensuring correctness. Type inference isn't perfect, so you may need to provide a
    type annotation in some situations.
  • impl PartialOrd for Month and impl Ord for Month; this assumes the months are in the same year
  • SystemTimeExt trait, adding methods for checked arithmetic with time::Duration and obtaining
    the difference between two SystemTimes as a time::Duration
  • Permit using UtcDateTime with rand (this was inadvertently omitted previously)
  • impl core::error::Error for all error types (now available when the std feature is disabled)
  • MacOS can now obtain the local UTC offset in multi-threaded programs as the system APIs are
    thread-safe.
  • #[track_caller] has been added to all relevant methods.
Changed
  • The minimum supported Rust version is now 1.81.0.
  • The dependency on itoa has been removed, as the standard library now has similar functionality
    by default.
  • Formatting a component that involves a floating point number is now guaranteed to be
    deterministic, avoiding any subtle differences between platforms or compiler versions.
Fixed
  • Serializing timestamps with nanosecond precision should always emit the correct value.
    Previously, it could be off by one nanosecond due to floating point imprecision.
  • A previously unknown bug in OffsetDateTime::to_offset and UtcDateTime::to_offset has been
    fixed. The bug could result in a value that was invalid. It was unlikely to ever occur in
    real-world code, as it involved passing a UTC offset that has never been used in any location.
Miscellaneous
  • The amount of code generated by macros has been massively reduced, on the order of 65-70% for
    typical use cases of format_description!.
  • Significant performance gains for comparisons of Time, PrimitiveDateTime, UtcDateTime, and
    OffsetDateTime. The first three have gains of approximately 85% (i.e. 6× faster).
  • Nearly all methods are #[inline].

v0.3.41

Compare Source

Fixed
  • Compatibility with the latest release of deranged. This fix is permanent and covers future
    similar changes upstream.

v0.3.40

Compare Source

Added
  • Visibility modifiers may now be added to the mod generated by time::sere::format_description!.

v0.3.39

Compare Source

Fixed
  • Doc tests run successfully with the default feature set.
  • wasm builds work again.

Both of these were regressions in v0.3.38 and are now checked in CI.

v0.3.38

Compare Source

Added
  • The [year] component (in format descriptions) now supports a range modifier, which can be
    either standard or extended. The default is extended for backwards compatibility. This is
    intended as a manner to opt out of the extended range when the large-dates feature is enabled.
    When the large-dates feature is not enabled, the modifier has no effect.

  • UtcDateTime, which is semantically equivalent to an OffsetDateTime with UTC as its offset. The
    advantage is that it is the same size as a PrimitiveDateTime and has improved operability with
    well-known formats.

    As part of this, there were some other additions:

    • utc_datetime! macro, which is similar to the datetime! macro but constructs a UtcDateTime.
    • PrimitiveDateTime::as_utc
    • OffsetDateTime::to_utc
    • OffsetDateTime::checked_to_utc
  • time::serde::timestamp::milliseconds_i64, which is a module to serialize/deserialize timestamps
    as the Unix timestamp. The pre-existing module does this as an i128 where an i64 would
    suffice. This new module should be preferred.

Changed
  • error::Format has had its source() implementation changed to no longer return a boxed value
    from the ComponentRange variant. If you were explicitly expecting this, you will need to update
    your code. The method API remains unchanged.
  • [year repr:century] supports single-digit values.
  • All format_into methods accept ?Sized references.
Miscellaneous
  • Some non-exhaustive enum variants that are no longer used have been modified to be statically
    proven as uninhabited. The relevant fields are doc-hidden and not semver-guaranteed to remain as
    such, though it is unlikely to change.
  • An unnecessary check when parsing RFC 2822 has been removed.
  • Various methods have had their implementations changed, resulting in significant performance
    gains. Among the methods changed are
    • util::is_leap_year
    • util::weeks_in_year
    • Month::length
    • Date::to_calendar_date
    • Date::month
    • Date::day
    • Date::from_julian_day
    • Date::to_julian_day
    • other methods that call into these methods
