See also two programs by Roman Korcek, both of them plug-ins for Total Commander (http://www.ghisler.com/):
- AddTime (http://www.angelfire.com/sk/thehacker/addtime/)
Useful when you need to change the time or date of many files by a specific amount. Example situation - your digital camera's clock has been set incorrectly and now all your pictures have their dates off by an hour. Now, instead of changing the individual properties of every file you just select them all, click AddTime Addon's button, select 1 hour, press Start, and you're done!
Also available in a free-standing version. - ReDate (http://www.angelfire.com/sk/thehacker/redate/index.html)
It works similar to the counter [C] in TC's Multi-Rename Tool, however, it is used for file dates (and times) only. Using ReDate you can change the dates of multiple files incrementally or randomly.
Back in DOS, I mostly used Charles Dye's (Web site defunct) TOUCH:
TOUCH.COM v1.08d 2003-10-05 C. Dye
GPL Freeware. Copyright 1996-2003, Charles Dye. No warranty!
TOUCH [filespecs] [options]
/D:date set to specific date /D set to today's date
/T:time set to specific time /T set to current time
/C=file copy stamps from file
/A:attr change file attributes
/P offer yes/no prompt /F:x set date format
/S recurse into subdirectories /M page output
Unless you use /D /T /C or /A, no changes will be made!
Try /D? /T? /C? /A? /F? or /M? for more info.
The local date format is DD/MM/YYYY; you may omit the year.
One of the most interesting options was /C= copy time stamps from another file.
