The Stamp application was designed to be a small command line tool that will change files' date / time stamp. For example STAMP *.EXE 1:00:00 5/23/96 will change the date / time stamp for all .EXE files to 1am May 23rd 1996.
If you omit either the date or time it will use the current date or time instead; STAMP . will update all files to the current date and time. NOTE: The 32-bit version will change all three dates; the creation, modification, and access.
