* Only process logbook timestamps for events we will keep
Since we group by minute we were previously processing
every timestamp. We can avoid this by making all the
minute checks use the unprocessed datetime since
the groupings will be the same regardless of timezone.
This reduces the number of datetime object recreations
by at least an order of magnitude.
