Thanks for the quick tutorial. I think the expiration time in seconds
would have been a much cleaner solution, but that would mean changing
all the downstream scripts. I used the regsub command to clean up
the date and it works just fine now.
Thanks again,
David

Heres something to think about
$ tcl
tcl>expr 08
Error: syntax error in expression "08"
tcl>expr 07
7
tcl>expr 010
8
Get the picture?
You are feeding expr what it thinks are octal numbers.
Since '8' is not a valid octal digit you get a syntax error.
The answer seems to be the question of
how are you going to strip off the leading zeros given by the
system date command.
My answer would be regexp, but, I leave that to you.
BTW,
try this:
tcl> clock seconds
948218715
tcl>clock format [ clock seconds ]
Tue Jan 18 13:02:30 EST 2000
tcl>clock format [ clock seconds ] -format %j
018
Another thing to think about is using clock seconds rather
then days to expire stuff.
That way you do not have things like years to wrap.
Of course should remind us of the year 2038 bug.
how is tcl going to deal with this one?
I would not want to come out of retirement
at 80 years old to fix this one. :)
