INSTALLTIME:date format

[Joe Wulf]

Jeff,

Thank you for the insight and direction.  I'll go explore the LC_TIME issue.  I agree that is the right direction, from what you've said, and the 
little I've read so far.

My process is a casual one.  Once in a while, I'll kick off some 
scripts.   A part of that queries the RPM database for what is installed and provides a structured formatted list back.  All the other data I 
can chop up as I need to.  When that date format comes back different 
ways, it is challenging to process consistently, since the returned data seems to vary so.  What I think I need is a way to prefix my rpm query 
with a command that preserves LC_TIME (or important aspects of it), set 
it temporarily for the duration of that shell script instance to what I want and then puts LC_TIME back (if necessary).  I'm not looking to change the whole 
system around, just to support my occasional need.

I'm going to start looking for a good understanding of locale and specifically the parts and pieces of LC_TIME.

Thank you.

R,-Joe

P.S. resent to the list (I apologize for the duplicate).
