.SET_DATE

   The .SET DATE and .SET TIME commands let you specify a date and
   time to be inserted in your file when you issue the Substitute
   flag pair, $$, with any of the appropriate date or time
   parameters. .SET DATE also sets the date for the .DATE command,
   which causes the date to appear in running heads.
