The Sequential Dates Dataset Form
The two dateastext datasets can produce dates in any format  however a specialized format code must be provided. In the example above, the date format code is yyyyMMdd HH:mm:ss and this will produce dates (as text) in a format like 20100521 15:23:34. Many other formats are possible  the table below describes the codes which can be combined to produce any desired date format.

other format patterns. 
tt 
The AM/PM designator defined in AMDesignator or PMDesignator,
if any. 
z, %z
