How accurate does the clock have to be for Tor's correct operation?
This is not a simple question. See:

My understanding is as follows: if your clock is m minutes behind (m
60), then Tor won't operate for up to m minutes after fetching
consensus for the first time (m minutes if it fetches at round hour
correct time, less if later), but should operate fine afterwards. If
your clock is up to 3 hours forward, Tor should operate correctly.
Accessing hidden services has stricter requirements (±1 hour?), but
apparently that has been fixed in alpha Tor versions.
Tor developers, feel free to correct me.
I think that Tor could include a switch for ignoring clock correctness
when verifying consensus, but this is apparently an ideological issue.
