Hi.

I have no idea what vixiecron is! All I know is that the cron on my CentOS Linux works like this. If that's vixiecron, then freut mich!

Code:
crontab -e
 
*/90 * * * * date >> /tmp/cron_date.txt
:wq
crontab: installing new crontab

If it didn't like it, I'm sure it would have complained. I'll tell you in about 85 minutes Smilie

But Jim Mc. is right. People don't often state their OS when they ask the question.

It didn't complain, and it doesn't work! Es freut mich nicht!

Code:
Thu Aug  6 20:03:01 UTC 2009
Thu Aug  6 21:00:01 UTC 2009
Thu Aug  6 22:00:01 UTC 2009
Thu Aug  6 23:00:01 UTC 2009
Fri Aug  7 00:00:01 UTC 2009


And what took it so long?
Code:
Thu Aug  6 21:00:01 UTC 2009

So much for that!

cron doesn't care how many times you invoke the same script file. So why not invoke it 16 times at the time you want it to run?

0 0 * * * * /usr/bin/cleanup
30 1 * * * * /usr/bin/cleanup
0 3 * * * * /usr/bin/cleanup
.
.
.
30 22 * * * * /usr/bin/cleanup

Without doing some research, and assuming that the SCO I'm familiar with might work differently, I would suspect that the 90 minute sequence of executing might be determined by the time of the last reboot.
