The first is the one in use: the peer's round-trip time. | | `lastSyncSecsAgo` | `peer_last_sync_seconds` | Since a sync message from it was applied (or the epoch changed). | -| `divergedForSecs` | `peer_diverged_seconds` | How long its heads have differed from ours with no sync message from it in between; absent while they match.

Long values precede a healing re-handshake ([`peers.md`](peers.md)). | | `syncThroughput` | `peer_sync_throughput_bytes_per_second` | Sync bytes per second over exchanges of at least 32 KiB, round trip taken off, smoothed. Absent before the first large exchange; comes with its age (`secsAgo`) since large exchanges are rare. This is the rate the peer delivers at in practice (its apply time included), not the path's capacity. | | `clock.offsetMs`, `.withinMs` | `peer_clock_offset_seconds`, `peer_clock_offset_within_seconds` | How far its clock is ahead of ours (behind if negative), give or take. Each PONG says when the peer answered, by its clock, which lies between our PING going and the PONG coming: within half the round trip of its middle, however unevenly the two ways took. Of its paths and the last 5 minutes, the narrowest bound is kept; a sample it contradicts (a clock set anew) replaces it at once. Absent before a PONG from it. | | `epoch`, `sameEpoch`, `heads` | — | What it last advertised; `sameEpoch: false` means we don't sync with it. | |
