If you are asking for a time-zone database, such as pytz
(http://sourceforge.net/projects/pytz/), then I think there
are two reasons for why no such code is included:
a) such a database is not available in standard C, or even
in POSIX. So it is not possible to provide this functionality
by wrapping a widely-available library.
b) no code to provide such functionality has been contributed.
Normally, b) would be the bigger issue. In this case, I think
there might also be resistance to including a large database
(as usual when inclusion of some database is proposed).
