DST Timezone in php.ini?

[jcanker]

I just upgraded from 5.2.x to 5.3.3 this morning, and am now confronted with the "infamous"

It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the
date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you
most likely misspelled the timezone identifier. We selected 'America/New_York' for '-5.0/no DST' instead in
C:\Inetpub\wwwroot\ATSTest\sys\class\class.calendar.inc.php on line 98

 

Previously I just let php pull the system time to keep everything accurate with DST.  Now that I'm having to use the date.timezone setting in php.ini, how can I tell it to factor in DST, or do I now have to manually perform a calculation in my methods/functions to check and adjust?  Or does it automagically recognize the DST by setting it to

date.timezone = America/New_York

(yeah, right...what are the odds of *that*?

PHP handles daylight savings automatically.

Wow...color me surprised...maybe I'm thinking too much of the early 4.x days

Thanks for the quick response.

Does it? I was using php 5.* and it didn't work for daylight savings (UK).

As long as the timezone information is up to date (ie, not using old DST rules) and you specify the right timezone, yes it should.

 

Note that, in simplified terms, GMT is a timezone while UTC is a standard. If you use GMT (UTC+0) as your non-DST timezone then you should be fine because it becomes BST (UTC+1) during the summer. UTC, however, does not change.
