GPSTimestamp getTime() is Off by One Month

[J0hannB]

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.

I have fixed this in my local copy by changing line 170 in src/GPSFix.cpp from t.tm_mon = month; to t.tm_mon = month - 1;.

I found this too! Thank you @hicklin But your build has error and cannot build without edition. 'timezone' identifier in 'getTime' func comes out of nowhere. Maybe you have missing commit or something.
