Often when I want a timestamp attached to a flat file and it isn't
necessarily the file creation date, I attach a special record that
subsequent programs can distinguish from the rest of the data.  Typically
it's the first record, with an asterisk in the first position and any text I
want following, eg:

  * Created by PGMNAME 2022-12-05 14:55

...but it could be anything.  Would something like that be applicable here?

Not sure what this would accomplish. If you have the timestamp in the base
name, all the generations despite its creation date will all have the same
name with different generation names.

For example if you created a GDG Base with  (YEAR =2022 MONTH = 01 DAY = 05
HOUR =08 MINUTE =19 SECOND =03)

USERID01.Y2022.M01.D05.H08.M19.S03

Now if a new generation is created it would just have .G0001V00  at the end
but it would still have same base time stamp.

i.e

USERID01.Y2022.M01.D05.H08.M19.S03.G0001V00

Even if a generation is created 10 days later or an an year later it would
still have the same base time stamp.

USERID01.Y2022.M01.D05.H08.M19.S03.G0021V00

The only way out of this is to create a base and generation at the same time
and it will just have 1 version which makes the whole point of using GDG's
useless.

You are better off creating individual datasets with a date timestamp.
