I need to be able to return the zone by it's numeric representation(
i.e. -0500 ). Like

Wed Nov 26 16:29:29 UTC 2003 -0500

by chance.

I cannot find a function to do this. Is it built in or can i request an
addition?

Thanks,

Zach

However, as I have posted here before, there is a bug in this
library which for some reason automatically increases the time zone
offset from UTC by one minute, so if you run the above examples on your
system you will probably see -0501 instead of -0500. This problem is
easily fixed by removing the line

I've just read your mail. I don't read nearly all discussions in
English now.

I think you are right. I intended to consider leap seconds. But, I
was in confusion.

Thank you for your report.
