API GET/position query

hi Anton,
on which field is the query to the api GET/positions with the parameters "from" and "to".
servertime, devicetime or fixtime?

We always use fix time.

I understood the difference between serverTime and deviceTime, but what is the fixTime?!
Is the deviceTime and fixTime the same, and only difference that fixTime is the legacy KEYWORD ?!
Because i see same values for both ( deviceTime and fixTime) ...
Where i can found explanations for Traccar times?!
Many thanks.

I would recommend searching forum. It has been explained before. Fix time is the location fix time. Device time is the time of the message. Usually it's the same, but it's not always the case.
