I actually thought about this but encountered a problem with the sign part 
(for example, +05:00). According to the documentation, "%+" and "%-" only 
work for output. I just tried again and got an exception (with 1.33). Maybe 
I am missing something here...
In any rate, it is easy to parse the offset part ourselves.

Again, thank you very much for your help!

By the way, shouldn't it be t-=td?
