The duplicate filtering used on aprs.fi filtered some last packets, due
to the rather ambiguous local-time timestamp jumping back:
http://aprs.fi/?c=raw&call=KT5TK-11
I'll have to improve that code a bit to ignore backwards-jumping
timestamps if there's enough real time passing, or if the timestamps
continue to roll on nicely after the jump backwards.
