[tor-relays] TOR notice.log is spammed with "Certificate not yet valid" warnings

Hi, since 0.2.3.6-alpha the logs of my instances are full of these messages: 14:56:23 [WARN] (certificate lifetime runs from Nov 3 16:15:34 2011 GMT through Nov 2 16:15:34 2012 GMT. Your time is Nov 03 13:56:23 2011 GMT.) 14:56:23 [WARN] Certificate not yet valid: is your system clock set incorrectly? Any idea how I can get rid off these warnings? Best regards, Klaus
