/*
* DATE.C - date internal command
*
* Comments:
*
* 08 Jul 1998 (John P. Price)
* started.
*
* 20 Jul 1998 (John P. Price)
* - corrected number of days for December from 30 to 31.
* (Thanx to Steffen Kaiser for bug report)
*
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
* - added config.h include
*
* 29-Jul-1998 (Rob Lake)
* - fixed stand-alone mode. Added Pacific C compatible dos_getdate functions
*
* 1999/03/17 ska
* bugfix: detection for invalid date strings.
* Now the whole string must match: ^\s*\d+(.(\d+(.\d*)?)?)?\s*$
* The numbers can be delimited by any character from the 7-bit ASCII set,
* which is printable, but not alphanumerical.
* One need not specify all three parts (in which case the delimiter
* may be omitted, too). If one specify;
* 1 number --> only the day changes
* 2 numbers --> month/day; year remains unchanged
* 3 numbers --> month/day/year
*
* 2001/02/08 ska
* chg: two-digit year -> 2000 if less than 80
* add: DATE /D and TIME /T
*
* 2001/02/14 ska
* fix: years in range 80..199 are promoted to century 1900
* allows to parse dates created with year100 bug (by Arkady)
