$GPRMC Valid Date and Time
Hi, I am using your M20048-1 GPS module.

Is there a guaranteed way to determine the GPS module has a valid date and time? Can I reliability use the "060180" to mark the date/time as invalid or is it possible the module may broadcast other dates that are invalid?

Hi, You need to wait until the module has acquired a fix before using the date/time on the RMC message.
