Presumably some people will be running live CDs (or USBs) on systems
where they don't have the necessary privilege to set the system time.
To address these situations, what might be more useful is to be able to
tell Tor to offset the system clock by a given amount to get the "real
time".  Possbily in connection with this there could be a setting which
would cause Tor to automically determine this offset at initialization.
