GPSTimestamp getTime() is Off by One Month #5
Description
The month of year field in $GPRMC sentences is indexed 1-12. This is also how it it is stored in the month class member of GPSTimestamp. In getTime(), however mktime() is called, which expects months be 0-11.
This results in the timestamp returned by getTime being off by one month.
