It seems strange to me too, basically it synchronizes with NTP immediately after the DHCP lease on my M8S+:
Code
Jan 01 01:00:17 M8S-Plus connmand[2191]: eth0 {add} address 10.60.0.55/24 label eth0 family 2
Jan 01 01:00:17 M8S-Plus connmand[2191]: ntp: adjust (jump): +1666538362.234929 sec
Oct 23 17:19:39 M8S-Plus connmand[2191]: eth0 {add} route 10.60.0.0 gw 0.0.0.0 scope 253 <LINK>
Oct 23 17:19:39 M8S-Plus connmand[2191]: eth0 {add} route 10.60.0.1 gw 0.0.0.0 scope 253 <LINK>
Oct 23 17:19:39 M8S-Plus connmand[2191]: eth0 {add} route 0.0.0.0 gw 10.60.0.1 scope 0 <UNIVERSE>
But this (line 2) is missing from your log. What regional settings are you using?
