World Time Zones

I found the master list of supported timezones at php.net very inconvenient since it's alphabetized by row rather than column and the areas are all on separate pages, so there's no way to do a global search. There is also no reference there for the timezone abbreviations. I put this page together as a (hopefully) more convenient place to look up a timezone.


Note that when setting the timezone in PHP (or in MODX), you do not want the abbreviation — just the primary name (e.g., America/Chicago).

I've included the timezone abbreviations in parentheses so you can use your browser's search function with them. They are not unique — a single timezone may be used in several different countries — and some of them will vary with the time of year depending on whether Daylight Savings Time is observed.


For MODX users: You want to paste the correct timezone into the MODX date_timezone System Setting. Go to System | System Settings, put timezone in the search box at the upper right, and press enter. Double-click on the Value field and enter the timezone, then click outside that area before leaving the page.

I would like to have created a separate listing by country, which is possible in PHP, but only if you have the correct list of countries and I couldn't find one anywhere.
