The idate command sets the system date format to the international standard.
IDATE
The international date format is DAY/MONTH/YEAR. For example, the date December 23, 1993, would appear as 23/12/93.
D3 retains this format until the format is reset to the United States standard or until D3 is restarted.
To reset the system date format from international standard to United States standard, use the udate command.
