It's not important with all of them, but some, like JT65 and JT9, that
use very strong error correction use algorithms that are somehow linked
to start times. Other modes like MSK144 designed for meteor scatter
don't care about time, but instead are looking for the data repeated at
very short intervals so that you can get it in a very brief reflection.

It's worth the time to read through K1JT's excellent help file for
WSJT-X, which describes the various modes.
