Thanks for picking up my slack!
Looks close to me as well, just one additional comment about resetting the 
uptime.

https://gerrit.osmocom.org/c/osmo-bsc/+/23234/6/src/osmo-bsc/bts.c
File src/osmo-bsc/bts.c:

https://gerrit.osmocom.org/c/osmo-bsc/+/23234/6/src/osmo-bsc/bts.c@564
PS6, Line 564:  /* if the BTS is not up, skip this update */
With this check I think the uptime will stay at whatever value it was before a 
BTS disconnected and only reset to 0 after the BTS reconnects.

Extended downtimes should be reported as 0 uptime in my opinion and not as a 
horizontal line at whatever value was reported last.

You could use osmo_stat_item_get_last() to check if the last uptime value is 
different from the new one and only report then.

PS6, Line 576:  uptime_seconds = difftime(tp.tv_sec, bts->uptime);

ACK
