A Dsec would be useful where time is perfectly well synchronised but the
system incorporates a fixed and known delay, such as might exist on a
remote station where the audio stream is decoded locally.

In the older WSJT 10 program, there is a control labeled Dsec where
the user?s UTC clock reading can be adjusted to manually synchronize
with your QSO partner?s computer. I wonder if this feature would be
useful in WSJT-X to help with FT8 decodes if your attempted QSO
partner?s computer clock appears to be off. It could be helpful if
they are starting transmit too early. Might be something for the
developers could look at.

Hi Jay,
WSJT-X is an Open Source application, considered contributions are
welcome but there are no guarantees of acceptance. Such a change is
possible although quite complex given that time is read in several
places and it would be disruptive of an already complex application to
maintain a separate source of time consistently. TBH we would prefer
that users take the relatively simple steps necessary to keep their PC
time synchronized to UTC, within a few milliseconds, automatically.
The new FT4 mode requires tighter control of time synchronization,
currently ?0.5 S, so manual setting is not really sufficient.
