You might try something like this:
After making a card field named "scripts" (just to see it work)
make a button with the following script:
I have been clicked 3 times
The last time was 12:22 PM
on mouseUp
  get script of me
  add one to word 5 of first line of it
  put the time into word 5 of second line of it
  put empty into last word of second line of it -- erase extra 'XM'
  set script of me to it
  put script of me into cd fld "scripts"
end mouseUp
---- end of script------
Note that the first two lines are simply comments and are
ignored by hypercard's message passing, but you can use
then for data. (of course, it can be more than 2 lines, and
can even use commas for separating items)
Also note that they don't need the "--" comment delimeter,
which is only necassay within a handler.
Objects higher up can access the script of the target to get
at the data, read it, modify it, etc.
