It may be more simple to keep a record of when the command was last run,
e.g. a re-directed current date MMYY to a file for when it was last
invoked.  Something along the lines of:

  type/cat the MMYY.file (contents) to a memvar
  compare memvar with current.date MMYY
    if different
      run the command
      re-direct current.date MMYY to MMYY.file
    else
      do nothing
  release memvar
  exit

You would need to 'seed' the process with a manual re-direction.  If you
want a general-purpose tool, as I think you do, then you'll end up with a
library of each 'foo' commands own MMYY.file file.

Cheers,
Paul.
