I have a few places in the code where I need to use the TimeZone. I can get the timezone name using DateTime::TimeZone . Is it reasonable to put the timezone name in a constant? Or should it be in a variable?

Probably the best way to go would be to throw all this data into a database table and use some AJAX magic... .
You would simply group by the Country code column.
You can construct the data you want from this table: http://www.datelib.de/Timezones.shtml.en .

Of timezone-based model fields (and their corresponding form fields, and some decorators), which you could use to at least store different timezone values per user (if nothing else).

The user's timezone offset is stored in another column like this: -6

Try Google's Closure ....

If all else fails, you can simply create your own hashtable with the long names and abbreviations .

For example, if the user travels somewhere, their zip code hasn't changed, but their timezone has is traveling.
