NMEA_ZDA_TO_UTC

Using a Sparkfun Artemis thing plus with Arduino programming, capture NMEA messages from the UART port of a generic GPS and build a $UTC message using the $GNZDA and $GNRMC for UTC date and time.
Send back the new NMEA messages to another UART.

I have to deal with a closed source data logger that need the Aplanix specific message "$UTC,AAAAMMJJ,HHMMSS.DDD " to work.

With this program we don't have to buy a new datalogger and/or Aplanix GPS.

Can work with any "FAST" Arduino SBC.

Note: I use the Serial1 RX pin to read data from the generic GPS and the TX pin of the same Serial1 to send data to the datalogger.
If you have an Arduino SBC with two Serial ports, you have to change the code..

Work only with 1 Hz NMEA messages, otherwise you have to change the code.
