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.

If the pattern yy is used for the year, the date service uses a 50-year moving window to interpret the value of yy. The date service establishes the window by subtracting 49 years from the current year and adding 50 years to the current year. For example, if you are running the webMethods Integration Server in the year 2000, the moving window would be from 1951 to 2050. The date service interprets 2-digit years as falling into this window (for example, 12 would be 2012, 95 would be 1995).
