TouchMax by 12noon LLC

Did you forget to set your camera's time to Daylight Saving Time? TouchMax can fix it as well of many other issues you might encounter with the creation or modification timestamps of your files and folders.

TouchMax changes the Creation-Time and/or Modified-Time of any files or folders. It can use an absolute time or one relative to the file's creation time, file's modified time, or current time.

Usage

TouchMax.exe [options] <pattern>

Option	Description
--dry-run	Display values without making changes
--set-files	set file timestamps
--set-folders	set folder timestamps
--recurse	process subfolders
--set-creation	change creation time of the files
--set-modified	change modified time of the files

Optionally, add the following options to increment, decrement, or set a date/time component.

Option	Description
--year +# or --year -# or --year =#	set the year
--month +# or --month -# or --month =#	set the month (January is 1, etc.)
--day +# or --day -# or --day =#	set the date (1-31)
--hour +# or --hour -# or --hour =#	set the hour (0-23)
--minute +# or --minute -# or --minute =#	set the minute (0-59)

+ increments that value by the specified number
- decrements that value by the specified number
= sets that value to the specified number

Optionally, add the following option to establish a base timestamp:

Option	Description
--base-time now	set timestamp to current time before modifying
--base-time created	set timestamp to file's creation time before modifying
--base-time modified	set timestamp to file's modified time before modifying

Process

TouchMax follows this process to set a file or folder's timestamp:

1. Set timestamp to current time (or to the creation time or to the modified time), if --base-time is specified.
2. Apply absolute values, if any.
3. Apply relative changes, if any.

Examples

Set Modified-Time of a file to the current date/time:

touchmax.exe --set-files --set-modified --base-time now Test.log

If you forgot to set your camera's time ahead one hour for Daylight Saving Time, you can set the Creation-Time of all JPG files in folder ahead one hour:

touchmax.exe --set-files --set-creation --hour +1 *.jpg

Set Modified-Time of text files to last month and ten minutes ahead:

touchmax.exe --set-files --set-modified --base-time now --month -1 --minute +10 *.txt

Set Creation-Time to three days before the Modified-Time:

touchmax.exe --set-files --set-creation --base-time modified --day -3 *.txt

Set a file's Modified-Time to 15 Sep 2008:

touchmax.exe --set-files --set-modified --year =2008 --month =9 --day =15 test.txt
