The timestamps are stored in an MPEix file as "longint_types" which are
double integers.

The big problem is that these dates aren't stored as a date and time combo
as such, but as "microseconds since January 1, 1970".

In Cobol the timestamps are defined as:

01 LONGINT-TYPE COMP.
   05  FIELD-1 PIC S9(09) COMP.
   05  FIELD-2 PIC S9(09) COMP.

When you pass this field to the intrinsic "HPDATECONVERT" it will convert
the longint-type to a real date such as 20050207 for Feb 7, 2005. Fine. I am
already achieving this without any problems. However, it does nothing with
the time as far as I can tell.

So, can anyone out there tell me how to convert a real date AND time
sequence (e.g. 20050307 12:34:56) to "microseconds since January 1, 1970"
for the impending AIF call to update the timestamps in a file?

TIA,
Brian.
