SAS Date and time

#1
Hi There

I would like to know if there is a way to know when a particular variable was populated first. For example if I have a table with one of the variables as "First Name", is it possible to know when was the "First Name" variable populated for that particular record.

May be a time and date stamp ...

Thanks in Advance.

I doubt it. The best SAS would be able to do would probably be to tell you when the entire dataset was created (i.e., read into SAS).
