Brian-
If you are into perl, it has a number of functions (gmtime, localtime) that do a
nice job of converting from epoch time to more usable formats. The perl camel
book has the needed info.
If you are not into perl, maybe this suggestion is moot.... or maybe you should
join the perl ranks...
Good luck
