Date display formats can have two sections. The first is required and contains the format for dates; the second is optional and specifies how to represent NULLs:
date-format;null-format

About 2-digit years
If users specify a 2-digit year in a DataWindow object, PocketBuilder assumes the
date is the 20th century if the year is greater than or equal to
50. If the year is less than 50, PocketBuilder assumes the 21st century.
For example:
1/1/85 is interpreted as January 1, 1985.
1/1/40 is interpreted as January 1, 2040.
You can use the following keywords as date display formats when you want PocketBuilder to determine an appropriate format to use:
[ShortDate]
[LongDate]
The format used is determined by the regional settings for date in the registry. Note that [Date] is not a valid display format.
Table 21-5 shows how the date Friday, January 30, 2008, displays when different format masks are applied.
