That didn't seem to be your main point. You seemed to want to get Asia/Urumqi 
time by either natural longituide or by Beijing Time, depending on context.

Ah, ok. The Python interperter prints repr(tz1), not str(tz1).

You could extract it from that string, but it would be better to get it from 
the object attributes.

I don't have the pytz module to hand; there seems to be good documentation 
here:

   http://pytz.sourceforge.net/

including example code to get various specific pieces of information out of a 
DstTzInfo object.

Please see if that helps you, and if not, come back.
