Hi Max,
LOG_GPS_ITOW is the time from Midnight Sunday gmt time in miliseconds. That in combination of the Log file date we should come up with a good time stamp. 24 x 3600 x 1000 I assume is the number of ms in a day. I haven't dumped a log but I did do the math on what I could read off a plot in QGC and it seemed correct.
I assume if it was presented in the NEMA ZDA format it would satisfy GPSBabel. I have mentioned this to Peter also about adding a GPX, KML converter in QGC. I would like it in log dump because I could dump camera trigger also.
ZDA - Data and Time
$GPZDA,hhmmss.ss,dd,mm,yyyy,xx,yy*CC
$GPZDA,201530.00,04,07,2002,00,00*60
where:
hhmmss HrMinSec(UTC)
dd,mm,yyy Day,Month,Year
xx local zone hours -13..13
yy local zone minutes 0..59
*CC checksum
Cheers
Steve
