Repeaters that need their clock set
Every advert a repeater sends carries a timestamp from its own clock. The analyzer compares that against when the advert was actually heard, and lists the repeaters that are badly off.
Repeaters heard in the last day
Only repeaters whose latest advert reached an observer in the last 24 hours are included, so everything here is on air right now. Select one to open its profile on the analyzer.

Why a repeater's clock matters
MeshCore uses advert timestamps to tell a fresh advert from a stale or replayed one. A node that has already heard a later timestamp from a repeater will ignore adverts that look older, so a clock that jumps backwards after a reboot can leave the repeater invisible to the nodes that knew it best.
A wrong clock also makes the analyzer's own numbers harder to trust, and it stamps the wrong time on anything the repeater originates.
Fixing it
Log in to the repeater as admin from the MeshCore app and use the clock sync in its management screen, or send clock sync from the command line. Either sets the repeater to your phone's time.
Boards without a real-time clock forget the time whenever power drops, so a solar repeater that browns out overnight will keep coming back here. If yours does, a board or add-on with a battery-backed RTC or GPS is the lasting fix.
The repeater's time is nowhere near real time, often days or years out. Almost always it has never been set, or it was set once and lost on the next reboot, since most boards have no battery-backed clock.
The clock was set and is roughly right, but it has wandered by minutes or is gaining or losing time quickly enough to get there. Worth a resync the next time you're logged in.
