Reply with quote

Hello,
please have mercy and don't laugh at me (a lot) but I have to ask this question:

I have a requirement to change "the system time" in our testing environment at will (LPAR running z/OS 1.10, DB2.CICS ...)

Developers would like to have "a time machine" to be able to run for example monthly application whenever they want having a system time set on the first day of the month.

Does anybody have any experience in this direction ?

Please do not hesitate to leave a comment icon_biggrin.gif

Regards!

I don't know if they are still available, but Data Ager and HourGlass were independent software vendor products that allowed you to specify the date passed to an application. We used these products during the Y2K effort which is why I'm not sure of their current availability.

Barring such a product, you really do not want to arbitrarily change the system date as that affects log files, scheduled tasks, and may make the LPAR impossible to IPL without significant work by the systems support group.

You may also want to look into TICTOC from Isogon, which is still in use, although I do not have experience with it myself.

We still have TICTOC (Time Interactive Configuration) in our shop, but it is owned by IBM since Isogon's acquisition by IBM.
And I see that IBM has renamed this product as 'IBM Application Time Facility for z/OS'

HourGlass is still available, but is now owned by IBM. There is also Validate, by ASG. We use both of these products.

HourGlass used to be a easier product to maintain and use until IBM acquired it...
