Re: QWCCVTDT API and *DTS format

Hi Peter,

*DTS is an unformatted 8 byte system timestamp. It's returned or used by
various APIs and MI functions - you can find an example of its usage if you
take a look at the Qsy_Rtn_Entry_Usage_Attr_T structure here:
http://as400bks.rochester.ibm.com/pubs/html/as400/v5r1/ic2924/info/apis/QSYF
IVLA.htm

For MOVE to convert character or numeric values to a timestamp they have to
be in the correct external format (which *DTS isn't) - so here QWCCVTDT
comes in handy...

Best regards,
Carsten Flensburg
