It is probably the best to calculate back to UTC.
Assume "2005-06-07 15:07:12" the local time, then convert it as
follows to UTC. Use the UTC time to store/manipulate/whatever you want
to do.
import time
t = time.mktime(time.strptime("2005-06-07 15:07:12", "%Y-%m-%d
%H:%M:%S"))
print time.ctime
Well, I'll admit I haven't ever used the Numeric module, but since
PEP207 was submitted and accepted, with Numeric as apparently one of
its main motivations, I'm going to assume that the pros and cons for
having == and ilk return things other than True or False have already
been discussed at length

There's no doubt that these problems could be solved in

i fixed it.
the program was going nuts because there were
