We use it busybox ntp for some time now, also with ntpclient since it is convenient. btw: ntpdate is removed from ntp some time ago. Why do you need a runtime configuration at all ? you can always restart with a new setup, write a small wrapper and you can use a file again. re, wh > Best regards. > Catherine > > On 11/23/2015 01:11 PM, Michael D.
