Well, you can demonstrate it fairly easily on the command-line:

$ TZ="right/UTC" date ; TZ="posix/UTC" date
Wed Jul  4 18:26:24 UTC 2012
Wed Jul  4 18:26:49 UTC 2012

What you need is a library that can easily open multiple timezones at once. I thought glibc could do it, but it doesn't appear to, from reading the source. However, GLib seems to have support. I would have thought the g_time_zone_get_offset() would be enough, but apparently not. Actually, even though I can open both zones I can't convince GLib to give me the answer :(. Though it must be possible.

Thanks for the pointer! If we had an easy way to get TAI I'd seriously consider using it in our internal systems since many parts already assume they can use simple substraction to get lengths of time intervals.
