Replace HermeticTxtFuncMap with TxtFuncMap to expose date/time
functions (now, date, dateInZone, etc.) while still excluding
security-sensitive env/expandenv functions.
Users can now use date functions in templates, e.g.:
{{ now | unixEpoch }}
{{ now | date "2006-01-02" }}

Summary
Fixes #2372 — Go template sprig date functions (
now,date,dateInZone, etc.) are not defined when usingsyft -o template.Root Cause
NewFormatEncoderwas usingsprig.HermeticTxtFuncMap()which intentionally excludes non-deterministic (time-dependent) functions. While this ensures reproducible output, it prevents legitimate use cases like embedding scan timestamps in SBOM templates.Fix
Replace
sprig.HermeticTxtFuncMap()withsprig.TxtFuncMap()to expose the full sprig function set, while explicitly removing the security-sensitiveenvandexpandenvfunctions to prevent accidental leakage of environment variables into templates.This allows template authors to use:
Testing
Manually verified that
now,date, anddateInZoneare available in templates after this change.Signed-off-by: Sputnik-MAC sputnik.mac.001@gmail.com
