[Zope3-dev] datetimeutils: add localize datetime?

[Gary Poster]

hi y'all.  Two related questions about datetimeutils.  I needed 
something to localize a naive datetime.datetime (i.e., add a timezone) 
on the basis of system time.  I decided to harden them using the 
approach in datetimeutils, so I leveraged some protected (_*) methods 
in datetimeutils and got something that does the job in five or six 
lines. 

My questions:
does something like this exist already? 
If not, anyone mind if I check it into datetimeutils? 

I'll probably test it by comparing the returned time against the same 
time with the dynamic (non-hardened) system-based timezone in the 
datetime library docs, unless someone has any better ideas.

Thanks

Gary
