Correct. The seconds taken at an instant in time will give the same
result no matter where you are and what time zone you are in.
Converting it to any other format then applies the time zone of the
computer doing the conversions.

As an example, my time zone is +1000 and at the moment, using this
line of script,  I get:

put the seconds & cr & the long time && the long date

1264484095
3:34:55 PM Tuesday, January 26, 2010

If you take that value of seconds and convert it, you will get
whatever time it was in your zone when it was 3:34 for me.

Cheers,
Sarah
