I'm not clear on exactly what you're looking for, but mxDateTime
claims to handle time zones, daylight savings time, leap secs, etc..
It appears to use UTC.

The Boost folks have a page with date/time links, including
C/C++ libraries:

http://www.boost.org/libs/date_time/doc/References.html

I don't use any of this stuff so I can't comment on its suitability.
I just happened to recall hearing of it.  I have a dim recollection
of a recent addition to the std lib that deals with dates and time,
but I may just be remembering an announcement of the latest
mxDateTime.
