cron does not run files at scheduled times

I have a SUN T2000 SOLARIS 10 and have been trying to get just a simple script to run in cron.
Nothing happens.  I do a ps -ef |grep cron
 # ps -ef |grep cron
    root   384     1   0   Sep 21 ?           0:03 /usr/sbin/cron
so it appears to be running.
Any suggestions as to why nothing is executed from cron?
I just put a script in there that simple echos a few lines to a file but that does not happen.
On my production T2000 SOLARIS 10 this same script runs fine.

Thanks

You are not giving us much to go on, are you? I think you need to be more specific about your particular issue. Right now all we have is
"cron is running. My script isn't. Why?"

What does your script look like? Which crontab is it in? What does the entry look like?  Have you looked in the cron log file under /var/cron?

The script will run only on 17:18 every day except sunday.

Are you in the time window,  to check if it working?

I keep changing the time trying to get it executed.
This script is just for testing because nothing is running from cron.
I did a svcs -a |grep cron and the service is online.
I did a svcadm restart cron as well but nothing runs.

One thing I forgot to mention is that I had to change /etc/TIMEZONE to be GMT - it was CDT - I just vi ed the file to make the change  - is that a problem?

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

change the line on to this:

* * * * /usr/bin/sh /var/tmp/b.sh  2>&1 >/var/tmp/b.log

it will run script every minute

then check your log "/var/tmp/b.log"
and check also cron log...

that ran
* * * * /usr/bin/sh /var/tmp/b.sh  2>&1 >/var/tmp/b.log

Does that mean something is messed up on the time because I changed the TIMEZONE file?

TIMEZONE can affect the schedule. but it still will run.
Also you should read the crontab format manual to understand how to create cron scheduled jobs

How are you editing the crontab file? Are you using the crontab -e command to do it?

If I remember correctly, changing the system time use to cause cron to misbehave in earlier versions of solaris
