converting HL7 date to MS SQL date in a BPL

• Reads the input string val as a time stamp in in format, and returns the same value converted to a time stamp in out format. See “Time Stamp Specifications for Filenames” in Configuring Ensemble Productions.
• The default for in and out is %Q. Any %f elements in the out argument are replaced with the file string. If val does not match the in format, out is ignored and val is returned unchanged.

..ConvertDateTime(source.{Z01(1):DateOfBirth},"%Y%m%d","%q(1)")

%q(1) is the format.

We had a consultant write this for us as well...
