$ PEEK/SAVE_SCREEN/LOG/REOPEN /TIME_OF_DAY = hh:mm
                                 /NOTIME_OF_DAY

   Specifies the approximate time of day when a new version of a
   terminal-logging file should be started (when /REOPEN is in
   effect).

   Use /NOTIME_OF_DAY to specify that any default /TIME_OF_DAY
   value should be ignored.

   The default value for this qualifier is taken from the logical
   name SAVE$TIME_OF_DAY.

   Example: $ PEEK/SAVE_SCREEN/LOG/REOPEN/TIME_OF_DAY=23:59

   The above command specifies that a new log file version should
   be created at 1 minute before midnight each day.

   Valid values for /TIME_OF_DAY are 00:00 through 23:59.

   Note that all 5 characters of the hh:mm syntax are required
   in all cases. Midnight would be specfied as 00:00. (The
   special value /TIME_OF_DAY=-1 is the equivalent of
   /NOTIME_OF_DAY and causes the qualifier to be ignored.)

   Examples:             The log file will be reopened at:

   /TIME_OF_DAY=00:00    12:00 AM
   /TIME_OF_DAY=00:01	12:01 AM
   /TIME_OF_DAY=01:00 	 1:00 AM
   /TIME_OF_DAY=12:00 	12:00 PM
   /TIME_OF_DAY=14:03	 2:03 PM

   Any /MIN_REOPEN value is ignored when reopening a file at
   the /TIME_OF_DAY specified.
