- I have the following little shell script, called timesynch, in
- /usr/local/bin. Once root starts it, it reruns itself every night at 3AM.
- Substitute your favorite ntp host...
-
- # timesynch shell script
- /usr/etc/ntp -s time.telcom.arizona.edu > /dev/null
- /usr/bin/sleep 900
- /usr/bin/at 3 /usr/local/bin/timesynch
