	      do not create any files

       -d, --date=STRING
	      parse STRING and use it instead of current time

       -F, --forward=SECONDS
	      Modify the time by going forward SECONDS seconds.  For example, touch -r foo -F 5 bar will make the file bar 5  seconds  newer  than
	      file foo.

       -f     (ignored)

       -m     change only the modification time

       -r, --reference=FILE
	      use this file's times instead of current time

       -t STAMP
	      use [[CC]YY]MMDDhhmm[.ss] instead of current time

       --time=WORD
	      set time given by WORD: access atime use (same as -a) modify mtime (same as -m)

       --help display this help and exit

       --version
	      output version information and exit

       Note that the -d and -t options accept different time-date formats.
