- Removed the timezone guessing algorithm in case the timezone isn't set with
date.timezone or date_default_timezone_set(). Instead of a guessed timezone,
"UTC" is now used instead.
- Removed old date/gmdate implementations.
- Moved date() related testcases to ext/date/tests.
- Implemented bug #33452.
- Fixed testcase for bug #27719 - there is no timezone called "EST5DST".
