Yes, that would do it. Ubik is very sensitive to time differences between
dbservers; it needs the times to stay within a few seconds of each other.
And, a large time step on a server may cause it to think it is no longer
coordinator, and/or disrupt its ability to vote. Depending on the nature
of the change, the disruption could last as long as 80 seconds plus the
amount of the time change.
