Setting NTP interval

How do I set in YAST the NTP synchronization interval? Regardless what I select in “Runtime Configuration Policy” the field “Interval of the Synchronization in Minutes” in disabled.

I would like to set the synchronization interval to 60 minutes - how to achieve this?

Thx

Forget YAST for NTP(d) configuration. You should configure NTP(d) manually (/etc/ntp.conf). Please read the manual page:

man ntp.conf
