The dates you use with a date service must adhere to the java.text.SimpleDateFormat class.

If you use an invalid date with a date service, the date service automatically translates the date to a legal date. For example, if you specify 1999/02/30 as input, the date service interprets the date as 1999/03/02 (two days after 2/28/1999).

If you use 00 for the month or day, the date service interprets 00 as the last month or day in the Gregorian calendar. For example, if you specify 00 for the month, the date service interprets it as 12.
