| I have a process that will post an entry into syslog periodically when
it is working properly rather than when it isn't. When the process
'breaks' this heartbeat entry will no longer be put into the log.
I need a script to monitor for a negative -- that is to say, I need to
know how many minutes it has been since the even happened last. Of
course, accounting for change of day, month and year.
Does anyone have a script that does this?

Does this do what you want:
while :
do
mtime=`stat -c "%y" syslog`
[ "$mtime" = "$prevMtime" ] && echo "No update!"
prevMtime="$mtime"
done

Adding a "sleep" might not be a bad idea ;-), e.g
sleep 60

| I'm sure the sleep would help quite a bit 
Is stat built into the shell? What shell are you using...
I think I can make this work, the shell script would be called by our
monitoring system (Tivoli ) then based on STDOUT or an exit code it
would generate the notification..

No, you can get it from FSF, e.g. http://directory.fsf.org/stat.html

It depends... normally ksh88 on Solaris, or bash on cygwin (yes, I know,
it's not a real OS, but it does what I want) on Windows XP.
