New option for time zone

[decibyte]

I like how there's already the -u option to get the clock to show UTC. How about another option to define a time zone, relative to UTC? E.g. -z +2:00, to be able to show CEST even without having the computer clock set to this time zone.

Along with #51, this would allow for awesome World Clock monitors, with multiple clocks showing the time in New York, London, Tokyo, etc. -- or any list of cities relevant for yourself or your business.

this is what the TZ environment variable is for. i don't think we should implement an option where there is already a standard environment variable knob.

That is brilliant, @anarcat. Thanks!

Oh, maybe -h/man should mention this?

[anarcat]

sure - the manpage could mention the TZ variable... we could take example on the date manpage and add examples with the variable...
