Input format for dates

The input format for dates is:

[YY]YY-MM-DD	[YY]YY MM DD	:	Year; choice of two-digit or four-digit entry
		:	Month
		:	Day

When the year is entered as two digits, LMS uses a reference year to add the other two digits for the century :

If YY < 60, LMS precedes YY with 20, i.e. 20YY, and

if YY ≥ 60, LMS precedes YY with 19, i.e. 19YY.
