Do NTP pool servers use gpsd?

Solution 1:

You could probably work out which of your current upstreams use gpsd by checking their reference id. I don't run gpsd, but some quick web searches suggest that it will probably show up as PPS or GPS. Then you could manually replace them before the known GPS week rollover date.

However, as long as you have sufficiently diverse upstreams and are using the pool with the pool directive in your configuration, you can probably do nothing and be fine. The reason for this is twofold:

1. Your NTP server will be monitoring its upstreams and if it notices a large jump from one it will ignore it.
2. The NTP pool automatically removes inaccurate servers within a fairly short time window.

It's probably fine just to check it before the rollover and check it again afterwards.
