You will have to change the date after you make your changes to the file.
I'm including a note that discusses the DMSPLU command for doing this.

Subject:      Changing a date of a file

There's a lot of OLDDATE, FIXDATE, MYDATE, etc. Assembler routines
floating around that cobble the FST date/time field to some arbitrary
value.  There's not much to writing one, but the quality and robustness
varies with the programmer.

IBM Marketing, in response to a secret Share requirement for a facility
to backdate status reports, forced VM Development to write DMSPLU and
include it in CMS, starting at Release 5.6.  It is distributed as a
MODULE on the S-DISK, and is OCO, of course.  My version (ESA 1.0/9201)
has 'DMSPLU V01M00 10/04/90 15.10' imbedded in it.

The syntax seems to be: DMSPLU  fn ft fm mm/dd/yy hh:mm:ss

Leading zeros seem to be necessary, or you get Rc=24.

The only drawback seems to be that it is inconvenient to invoke it from
FILELIST, due to the slashes in the syntax.  You may want to cover the
module with an exec and change the date syntax to use dashes, instead.

Enjoy!
