Description |
The LongDateFormat variable provides the long (extended) formatting used for certain date to string conversions.
It is used by the DateTimeToString routine when the 'dddddd' formatting is used.
The following formatting character strings can be used in the LongDateFormat string:
y | = Year last 2 digits |
yy | = Year last 2 digits |
yyyy | = Year as 4 digits |
m | = Month number no-leading 0 |
mm | = Month number as 2 digits |
mmm | = Month using ShortDayNames (Jan) |
mmmm | = Month using LongDayNames (January) |
d | = Day number no-leading 0 |
dd | = Day number as 2 digits |
ddd | = Day using ShortDayNames (Sun) |
dddd | = Day using LongDayNames (Sunday) |
|
