I am working on time zones here. Does unix provide any utility which gives difference bet UST and local times in terms of secs.

I am ware of the TZ varibale which gives me the diff, but i want something in seconds.

Timezones are all integer multiples of an hour. So if you know the offset from GMT just multiply by 3600 to get the offset in seconds.

Not all timezones are multiples of an hour.  There are a number of timezones that are 30 mins diff and even one that is 45 mins (from memory).

raj_paps, are you willing to use Perl?

No.  There are no environment variables that can give you that information.
