          |      touch [-d <date>] [-t <time>] {<pathname>}

          |      Every file system object has a field indicating the date and
          |      time  (to within 4 seconds) it was last modified.  This com-
          |      mand will set the date/time modified field  of  file  system
          |      objects.

          |      The  "-d" option may be used to specify a date as recognized
          |      by the 'parsdt' routine; if no date is  specified  then  the
          |      current  date  is  used.   The  "-t"  option  may be used to
          |      specify a time as recognized by the 'parstm' routine; if  no
          |      time is specified then the current time is used.

          |      The  remaining  command line arguments are taken as names of
          |      files for which to  set  the  modification  time.   If  "-n"
          |      appears  in place of a pathname, pathnames are read from the
          |      standard input.  For more information on  this  syntax,  see
          |      the entry for 'cat' (1).
