Thank you for your comments, I have tested Time::HiRes ( gettimeofday ); on both Win2k and Slackware and both seem to work fine. Thanks for the heads up on the opening parens.. thats what you get when you can't copy and paste from a vmware session..

I have also tested this on two other machines and get similar results, where several of the gettimeofday()results have the same time.

I am only creating one tmp file from the cli at a time. However several of these clis run simultaneously. which caused me to get files with the same name...

I think I will have to look to a database.
