The strftime function has a (apparently undocumented) specifier, %z, on my
system.  It returns an rfc822 numeric timezone, an offset from GMT.

I don't know how portable this is, considering it's undocumented.  You may
want to use the Time::Timezone module, which provides the tz_local_offset and
tz_offset functions.  Alternatively, you can use the Date::Format module's
strftime function, which documents the %z, and has quite a few other
specifiers besides.  Both modules can be found on CPAN.

With any of the solutions you're going to get -0800, instead of just -8. 
This is to allow for half-hour timezone offsets, as well as offsets above 9,
while still being easy to parse.
