Thanks both for responding. It's OSX10.4, the clock is synchronized via
NTP, openssl is the latest port, and the problem affects any application
using Tor - curl, polipo, tsocks and even tor-resolve time-out in a
similar way.I have seen messages to the effect of 'client request when we no longer
have a valid consensus' and also 'very long circuit build time -
assuming clock jump'. I think it more likely that Tor is freezing ( I
see no increase in cpu time at all with 'ps') sometimes and therefore
the clock appears to jump when it unfreezes. Is that a possibility?
