Description Alexei Ababilov 2013-08-09 19:15:47 UTC

ntp-client.service starts /usr/sbin/ntpdate immediately, before network connection is established:

$ sudo systemctl status ntp-client.service 
ntp-client.service - Set time via NTP
   Loaded: loaded (/usr/lib64/systemd/system/ntp-client.service; enabled)
   Active: failed (Result: exit-code) since Fri 2013-08-09 21:26:12 EEST; 11min ago
  Process: 3294 ExecStart=/usr/sbin/ntpdate $NTPCLIENT_OPTS (code=exited, status=1/FAILURE)

Comment 1 Alexei Ababilov 2013-08-09 19:22:50 UTC

This is a proposed solution that uses Fedora's ntpdate-wrapper that runs ntpdate several times with a growing delay between attempts:

Comment 2 Alexei Ababilov 2013-08-09 20:19:23 UTC

Another solution is just to

sudo systemctl enable NetworkManager-wait-online.service
