Ohhh, I forgot about it. I have three versions of that function as there 
are three ways of getting the zone. The POSIX way is to call tzset() 
which sets global "timezone" variable holding the difference in seconds 
between GMT and your local time, the other is the glibc way - glibc 
adds tm_gmtoff member to struct tm, and stores what timezone variable 
would hold and the third way is what you saw in the ::zone() which 
doesn't depend on any of the above but is painfully slow. I'll add 
checks for the first two to configure.in and make it use the right one.

Sounds good, I'll fix the ::zone thingy and commit.
