Reranko05 opened a new pull request, #49953: URL: https://github.com/apache/arrow/pull/49953
### Rationale for this change As discussed in PR #49887, the Gandiva datetime test utilities currently use `mktime()`, which interprets timestamps as local time and can behave differently across platforms and DST boundaries. This PR switches the test utilities to `timegm()` so timestamps are interpreted consistently as UTC. This also removes the existing workaround logic in `Epoch()` that was previously needed for `mktime()` behavior on Windows/MSVC. ### What changes are included in this PR? * replaced `mktime()` with `timegm()` in `date_time_test.cc` * added a small Windows compatibility mapping for `_mkgmtime` * removed the existing DST/localtime workaround logic in `Epoch()` ### Are these changes tested? * Re-ran `DateTimeTestProjector.TestFromUtcTimestamp` repeatedly locally * Re-ran the full `gandiva-projector-test` suite successfully ### Are there any user-facing changes?
