Looking for a list of Perl supported Timezones

[ajdavis]

I have a web gui that allows users to display all datetimes in the timezone of their choosing from a drop-down list using the following code:

$result = time2str($template, $time, $timezone);

What I am looking for is the list of acceptable timezones that can be sent in as the third parameter in the call to time2str. Is there a programatic way to retireve that list or is the list compiled on-line somewhere that I can just hard-code into an array? I've been searching, but so far, no luck. I want to display this list to the user for them to choose from. Thanks in advance for any help.

Not sure if it's correct or not, but here's a web resource that shows the abbreviations of all the timezones in the world.

DateTime uses the Olson Time Zone database (

http://www.twinsun.com/tz/tz-link.htm)

to support accurate time zone handling for all time zones in the world.

Found the above information at:

Let us know your results!

Sorry it has taken me so long to respond.

The time2str function can take either a timezone abbreviation or the +- offset from GMT as the third parameter, so what I have decided to do is create a hash for displaying timezone options to the user in a dropdown list. This hash will contain a pseudo time zone abbreviation (abbreviations that we will control) as the key and a descriptive string as the value for displaying in the dropdown. I will also have a second hash that uses this pseudo time zone abbreviation as the key and the GMT offset as the value. So once the user chooses the "time zone" that they want their date/times displayed in, we will use the corresponding offset to calculate the new datetime. This way it will be a little more flexible on what we can offer and hopefully lessen, if not eliminate, any clashes in timezones that use the same abbreviation.

Thanks for everyone's input.
