question: in signalk server, how does the server deal with updates with timestamps older than existing data? does the server filter/ignore updates with older timestamps than existing data?
context: in the marinetraffic-public plugin I pull AIS data from marinetraffic for vessels. i set the timestamp in the generated delta to be the timestamp of the data from marinetraffic; which sometimes can be hours old.
I was looking at some odd data and I'm trying to figure out whether signalk is correctly filtering potentially "old" updates vs much up-to-date information from e.g. NMEA AIS receivers?
