Comment (by SergeyBiryukov):

 In [changeset:"45424" 45424]:
 {{{
 #!CommitTicketReference repository="" revision="45424"
 Date/Time: Replace all instances of `date()` with `gmdate()`.

 Use of `date()` in core depends on PHP timezone set to UTC and not changed
 by third party code (which cannot be guaranteed).

 `gmdate()` is functionally equivalent, but is not affected by PHP timezone
 setting: it's always UTC, which is the exact behavior the core needs.

 Props nielsdeblaauw, Rarst.
 Fixes #46438. See #44491.
