… agent
_schedule_agent read the model's `timezone` argument only when the user
record was missing, which never happens for an authenticated caller, so a
timezone the user picked in chat was discarded in favour of their profile
default. Precedence now mirrors POST /graphs/{graph_id}/schedules: explicit
timezone, then stored preference, then UTC. An unknown timezone is refused
rather than silently downgraded to UTC.

🤖 Mutation evidenceEvery new test was proved able to fail by mutating the fix back out and re-running. Each mutation asserted its own match count, so a mutation that silently applied to nothing would have aborted rather than reporting a false pass.
Mutation A reproduces the QA report exactly — the schedule lands in Executed suitesThree tests in Runtime facts checked on this machineThe first is why an unvalidated timezone reaches the scheduler as an opaque RPC error; the second is why the existing helper is the wrong instrument for a value the model has already read back to the user. |

WalkthroughAgent scheduling now resolves explicit, stored, and fallback timezones. Invalid explicit timezones return an error before library-agent creation. Tests cover each resolution path and verify scheduler and library-agent call suppression. ChangesTimezone scheduling
Priority: ⬇️ Low — Defer this scheduling change because it is limited to timezone selection, validation, and fallback behavior for AutoPilot agents. Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to Scheduling now uses an explicit timezone, then the user preference, then UTC, while rejecting invalid timezones before creating schedules or library agents.

⚠️ Verdict: Review incomplete — product specialist did not complete; fix the review setup or missing evidence and rerun.
A focused, security-positive backend fix that removes a dead branch and restores explicit→stored→UTC timezone precedence in AutoPilot scheduling, validating the model-supplied timezone before use. Covered by four targeted tests; CI green on the reviewed head with no defects found.

autogpt_platform/backend/backend/server/v1.py:2561Consider lifting validate_timezone into the REST schedule endpoint for parity — The copilot path now pre-validates the IANA timezone, but the REST POST /graphs/{graph_id}/schedules path still passes an explicit timezone through unvalidated, so the two entry points agree on precedence but differ on validation strictness.
Suggestion: Optionally apply the same validate_timezone pre-check in the REST endpoint so both paths reject bad timezone names identically.

Specialist Reports
| Specialist | Status | Summary |
|---|---|---|
| security | ✅ PASS | A correct, security-positive fix that validates the model-supplied timezone before use and restores intended explicit→stored→UTC precedence; no security defects found. |
| architect | ✅ PASS | Sound, well-scoped fix that restores the advertised timezone precedence in AutoPilot scheduling, mirrors the REST API contract, adds appropriate invalid-timezone refusal, and ships with durable comments and adequate tests. |
| performance | ✅ PASS | Timezone precedence fix introduces no performance regressions and slightly reduces DB/RPC work on the common and invalid-input paths. |
| testing | ✅ PASS | Correct timezone-precedence fix with four focused, assertion-strong tests covering each branch and a proper no-side-effect negative case. |
| quality | ✅ PASS | Focused, well-tested fix that removes a dead timezone branch and aligns copilot scheduling precedence with the REST API; no code-quality defects found. |

Why / What / How
When AutoPilot schedules an agent, the schedule is now created in the timezone the user actually picked in the chat, instead of their profile default.
The v0.7.5 release QA reproduced the bug end to end against dev-builder: asked to schedule an agent daily at 10:00, AutoPilot asked which timezone through its question widget, was told
Europe/London, and confirmed back "every day at 10:00 (Europe/London)" — butGET /api/schedulesreturnedtimezone: "Europe/Amsterdam", an hour off in absolute terms. The user was told one thing and got another.The cause is one line in
_schedule_agent:get_user_by_idraises on a missing row rather than returningNone, so theelsebranch is unreachable and the model'stimezoneargument was never consulted. The tool schema still advertised it, which is why the model asked the user for it at all.The precedence is now the one
POST /graphs/{graph_id}/schedulesalready documents and implements — explicit timezone, then the user's stored preference, then UTC — so the copilot tool and the REST API agree. Thetimezonefield's default changed from"UTC"to"", because with a"UTC"default an omitted argument is indistinguishable from an explicit one and would have overridden every user's stored preference.An unknown timezone is refused with an
invalid_timezoneerror rather than silently falling back.get_user_timezone_or_utcswallows an invalid value to UTC with only a log line, which for a value the model has just read back to the user would recreate the same class of bug; and letting it through reaches the scheduler as an opaqueZoneInfoNotFoundErroracross the RPC boundary. This mirrors howschedule_followuppre-validates cron locally, for the same reason.No caller depended on the old behaviour: the frontend scheduling UI never sends a per-schedule timezone (it only displays the profile one), so it was already on the fallback path.

Checklist 📋
For code changes:
Verified. I executed the four new tests plus the six pre-existing
test_run_agent_schedule_*tests (10 passed), the other 26 tests inrun_agent_test.py,backend/util/architecture_test.py(3 passed) andbackend/blocks/test/test_block.py(1647 passed, 84 skipped). Each new test was proved able to fail by mutating the fix back out — see the comment below for the mutation table. Three tests inrun_agent_test.pyhang on my machine (test_run_agent,test_run_agent_with_llm_credentials,test_run_agent_with_use_defaults), all on the real-execution path this PR does not touch;test_run_agenthangs identically with this branch's changes fully reverted todev, so the hang is environmental and I am relying on CI for those three. I did not exercise the fix through a live AutoPilot chat.
