Changeset 45424 for trunk/src/wp-includes/post.php

Message:

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.
