on line 357, GF(GSM_NL "+QGPSLOC:" should be replaced by GF(GSM_NL "+QGPSLOC: " (with a space at the end before the dopple quotation mark) to solve a parsing problem. when you try to get the time the data will be wrong, because out of a NMEA-msg:
+QGPSLOC: 083244.0 ......
the time should be as following:
hh: 08
mm: 32
ss: 44

however because of the space the getGPS method will consider the space as a digit and give for that reason the following time:
hh: 0
mm: 83
ss: 244

ihour = streamGetIntLength(2); // Two digit hour
here the space will be considers as digit

the suggested solution at the top would solve the problem
