Re: [Paparazzi-devel] UTC and gps:itow in log files

[Marc Schwarzbach]

Dear Henri,

thats an issue with the leap seconds reflected in UTC 
http://en.wikipedia.org/wiki/Coordinated_Universal_Time

GPS overall time has started in the 80s and does not count for them. 

Should be a searchable issue...

Cheers

Marc
