Cool, I guess that must be new; I brought up a new 13.1 VM and see that YaST now also allows a synchronization interval, which is cool. Thanks :) Chris

The biggest reason I need to do one-offs is I've had issues with time drift on some of my VMs, and enabling NTP in YaST only runs a time sync on boot.
certainly not. in brand new 13.1: ps ax | grep ntp 3486 ? Ss 0:01 /usr/sbin/ntpd -p /var/run/ntp/ntpd.pid -g -u ntp:ntp -c /etc/ntp.conf the *daemon* is started at boot jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Wait. In a virtual machine you should not normally be using NTP. For instance, in the vmware documentation they warn against it. Instead, they recommend that you set the guest to just sync to the host, using guest tools. There is a setting for this in the main configuration of the machine. I guess it is a waste of resources. Just use NTP on the host, and sync guest to host. Even more recommended if you run several guests. -- Cheers / Saludos, Carlos E. R. (from 12.3 x86_64 "Dartmouth" at Telcontar)
For some reason, some of the VMs (but not others) have still had issues with time drift even though VMWare tools was installed and set up to sync with the host. Typically that would point to a loading issue, but not in the case of these vms/hosts. So to keep things happy, we just had them periodically sync with our on-campus NTP server. For my personal, non-work-related needs, I have my laptop and home server (both oS) set up to stay in NTP sync because it's helped with some of the issues I've had with OwnCloud wanting to re-download random files repeatedly even though nothing's changed. Although, it looks like that's going to be resolved shortly because it looks like they found out the source of the bug. Chris

Not so new. It's present in YaST on 12.3 as well.

Come on, people. ntp has a long tradition in SuSE, openSUSE and SLES as well. In former times, you needed to configure and run {x,}ntpd manually. I even managed to get a patch upstreamed, that allows to use USB2Serial converters to drive simple serial DCF77 clocks, so yes, I use ntp since ages, (ähem, 1998 at least), sync _all_ my systems from redundant DCF clocks.
