The LogFile went to DASD, and the create date was in the VTOC information,
For tape files, CA1 would record the create date also.
The GDG Base itself had a create date of early December, The Files in the
GDG would have create dates when they were created by the +1 ..
Note the 23:00 to 23:59 log would have the create date of the "Next Day" as
it was created just after midnight, but the GDGBase it was written to had
the correct log date. (most of the time), Not sure when the logic in their
log program switched it to the "next" day. If the application was down from
~00:00 to ~ 00:15 it would then switch to the "next day" for the logs
writting.
Really was not a issue, when the application teams were aware of that issue
and would code the "next days" gdgbase in to get and random next day data.

So how would the GDG base definition would look like so that all the tape
GDG has creation date ?

Years ago, we had a vendor application that was setup to create a Hourly
Log File in a GDG.
Sometime in early December a Step in the Monthly Cycle jobs would create
the GDG's for the next year (A program created 366 Define GDG Cards) ,
Then
trigger a "Admin" job that had the authority to create GDG's.
GDGnames were Pxx.ApplName.LOGFILES.Syymmdd with one for each day of the
year.
Internal to the application it knew what date it was from the system
clock, and starting at 1am (local) would create a +1 Generation (with
the
00:00-00:59 Logs) at 2am next one ... with the correct GDGbase Name.
I think we had something like 250 cycles defined in the base, incase of a
restart of the application it would create a new +1 or a system IPL ..
The Application code never could figure out Daylight Saving time.. Also
was clueless on leap year, it would create Feb 29th every year even if it
was not a leap year.
We had other application that did log files at "Flat Files" with Date and
Time as last two nodes of the dataset names that were generated
dynamically
when created.

Subject: GDG with timestamp
Hi
Apology for the dummy question
For the GDG to have timestamp on its every generation, how do I ensure
that
timestamp gets appended with all that generation created ?
Could someone please point me as I am little confused here.
Peter
