That's weird... The line "time-sync-command=" make it look like it shouldn't try to time sync...

This error was not caused by sync command, I think timeout occurred to connect time server. By default, time.bora.net timeserver we use. We can set the timeserver by SEBAK_NTP_SERVER env or --ntp option.

[Geod24]

Why would sebak try to connect to the time server if sync is not configured ?

[spikeekips]

@Geod24 At the start time, it tries to check the system time is correct or not using timeserver.

[Geod24]

Sounds like a terrible thing to do. Either leave it to the system, or checks with the other nodes, not a random 3rd party.

@Geod24 only without time command is empty, it does not sync. Time server has default value and check time.
