The overall time calculations weren't really the issue last time
around. The problem was with sub-second sleeps and the thread
scheduler being confused and spinning when ntp inserted an extra
second in the clock. Any other way of resetting the clock fixed it.
(e.g. date -s "`date`"). It was a kernel bug and is theoretically
fixed now.
But I agree that those open bugs on the tzdata package aren't all that
helpful except to show that someone is thinking about it.
