Hi all,
I checked a few webtunnel bridges, and their "First seen" dates are all showing "1970-01-01 00:00:00". https://metrics.torproject.org/rs.html#details/7A78527DBDB7EFF85E5AA926A1B92... https://metrics.torproject.org/rs.html#details/6996BC2264025E9A87D51324CF56B... https://metrics.torproject.org/rs.html#details/81895A2C4E22E861615DD91275439...
Right now the bridges show some different and potentially reasonable dates. I am not sure what happened in the case of those bridges but we do have cases where firs_seen dates get reset to the epoch. See: https://gitlab.torproject.org/tpo/network-health/metrics/onionoo/-/issues/40...
For the top relays, I checked a few, and instead of showing the year 1970, they showed dates with times exactly at certain hours. I feel like this kind of coincidence is weird.

Is this correct behavior?
For the relays, it seems so for the bridges re-setting the first seen date to the epoch is certainly not. Georg
