The Things that Make Up this Example | To Execute this Example |
This form (VL_SAM151) acts as a simple interface to system variable *CENTRAL_DATETIME.
*CENTRAL_DATETIME is a user defined tier aware system variable that extracts the a date/time stamp from the current DATA tier ( the decision to define date/time as something that comes from the DATA tier rather than the APPL tier is a completely arbitrary and you could of course change it ).
A system variable like *CENTRAL_DATE time might be used to give all client systems a date and date stamp sourced from their common DATA tier rather than relying on their own date and time.
