Re: [chrony-users] Chrony problem - not synchronizing time

[Tino Mihajlovik <tinomk@xxxxxxxxx>]

Before the GPS is working, PPS is not locked to anything, it is marked with ? sign same as on start.

PPS is hardware pin from serial port

Here is the config file.

Attachment: chrony.conf

So when GPS locks it has valid time but at this moment PPS is already selected as source with *, and chrony is rejecting the NMEA messages with the valid time and system clock is not synced. I have noticed that during this time GPS source is marked as - or x.
