How often does a AREDN-node sync the time with the ntp-server defined under setup? It seems to me, that this is done by the node only once at startup. So if the ntp-server is not available at startup of the node, the time will not be synced any more later. Is that correct or do I have a wrong setup in my AREDN-Node?
In my case I have a Mikrotik hAP Router and a Pi configured as NTP-Server with GPS-mouse. The Pi is connected to the USB-Port of the Mikrotik for being supplied with current. This means, that the Pi is always starting up after the Mikrotik completely booted and the Mikrotik does never have a time sync with the NTP-Server of the Pi. Other nodes in the mesh get the time correctly synced with the NTP-Server of the Pi.
So is there any possibility to delay the time sync after booting up a AREDN-node?
Thanks for any helpful information.

Hi, Dan:
All my devices reference UTC, some display EDT/EDST, some display UTC.
example:
My workstations display local.
My WSJT-X station displays UTC.
3s, Chuck
I have just discovered the same race condition between the nodes and my Raspi which runs an ntp server (chrony). My ntp server uses a GPS receiver which may take a few minutes to lock. So precise time information will only be available some minutes after startup.
Even at startup the nodes do not always sync the time, only when e.g. the time zone has been changed. Especially for testing purposes it would be good to be able to force a node to submit an ntp request in order to sync time. In the latest OS supposedly a node syncs only once a day. This may be useful in a permanent setting, but for mobile settings there should be a sync every few minutes, at least if there is any meaning to the time the nodes are holding.
