First the job could call PKZIP or whatever to zip all new or changed files
into a file T$UPDATE.ZIP . Then it could call a small C or Fortran program
which could generate the name `ddmmyy.ZIP' and rename T$UPDATE.ZIP as
ddmmyy.ZIP. But a better choice of name would be e.g. $Uyymmdd.ZIP , so that
in a listdir sorted into filename ascii order all these update zip filenames
would come together in date order.
