Frequently asked questions

What output can this analyzer read?

It recognises four common formats: 'ntpq -p' (the peer table), 'chronyc tracking' (overall sync status), 'chronyc sources' (per-source tally), and 'w32tm /query /status' (Windows). Paste any one of them and it auto-detects the format.

Does the analyzer send my data anywhere?

No. All parsing happens in your browser with JavaScript. The pasted text never leaves your machine; nothing is uploaded to a server.

What problems can it detect?

Stratum 16 / unsynchronized state, reach 0 and .INIT. (unreachable sources), no selected sync peer, false tickers and outlyers in the tally, a large offset above the panic threshold, Leap Indicator 'not synchronized', and on Windows a stale Last Successful Sync Time or a Local CMOS Clock source.
