Date/time support
Date/time support has been fully rewritten in PHP 5.1.x, and no longer uses the system settings to 'know' the timezone in operation. It will instead utilize, in the following order:
- The timezone set using the date_default_timezone_set() function (if any)
- The TZ environment variable (if non empty)
- "magical" guess (if the operating system supports it)
- If none of the above options succeeds, UTC
To ensure accuracy (and avoid an E_STRICT warning),
you will need to define your timezone in your php.ini
using the following format:
date.timezone = Europe/London
The supported timezones are listed, in this format, in the timezones appendix.
Also note that strtotime() now returns FALSE on
failure, instead of -1.
