[Eclug] File creation times

Hi,

         there is a stat command in PHP and the filectime and fileatime are 
subcommands that extract one piece of information from the array that stat 
returns. It makes things a bit easier and saves about one line of code.

         I looked at my Windope box running NTFS and most creation dates 
are after the last modified date. I guess it resets the creation date when 
I copy a file, which should be treated as a modification (new location, not 
a new file). I guess I need to add a calendar control and have the date 
picked manually. Ah well....

         Thanks for the reply.

                 David K.
