The DATE command allows you to set or change the date known to the system.
The command format is as follows:

             DATE [mm-dd-yy]

It is a very good idea to set the date when the machine is started or reset
since the date stamp is updated on all files you modify while the system
is running.  Selective backups may be made on files modified after a certain
date, or you may need to know the last time a file was updated should the file
become corrupted.

Entering the command without parameters displays the current setting, and
prompts for a new date.  If the Enter key is pressed as the first key, the
date remains unchanged.  If the command is entered with parameters or you
want to supply a new date when the prompt appears, the inputs must be in the
following form:

  mm  - one or two digit month from 1 to 12.
  dd  - one or two digit day from 1 to 31.
  yy  - two digit year from 80 to 99 (a leading 19 is assumed) or a four
        digit number from 1980 to 2099.

The delimiters may be either hyphens "-" or slashes "/".
NOTE **  The system normally prompts you for the date when the system is
         started and usually does not need to be set again until the system
         is restarted or reset.  If you use an AUTOEXEC.BAT startup batch file
         you will want to include the DATE command in the batch file, otherwise
         the date is not requested.  For more information see page 2-15 in
         the DOS 2.10 manual.
