Re: File Last Changed

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

Yes.  In fact I do a "Save The World" (GO Save 21) both before and after 
applying PTF's.  The time portion indicates that it was close to the 
latter since I clocked out about 20 minutes later (my boss stayed to 
pull the tape for off-site storage).
