Diego,
Yes, I have a touch-date as well. I have already built one with this
method, in this case and like the read date, it does not update the
modified (and of course created) timestamp. this means the modified date
remains meaning as it should, the last time it was modified.
This is one reason I would like to see free access to custom buttons that
do a time stamp because if not available people start using created and
modified for other purposes, when being able to maintain valid created and
modified is important.
Also as I stated previously one of the easiest ways to deal with periodic
tiddlers such as say weekly, is each time you action it stamp the
weekly-date with now, and have you list use the weekly date to see items
older than 7 days.
Thanks for sharing your uses.
