Hi All,

Can anyone provide information or a link to a resource regarding the time stamps on PixHawk dataflash logs? I can't seem to find any up to date information on all the values recorded.

Specific example:

I have a row in a log where the first row has:

BARO_TimeMS=15354

and the corresponding GPS log is

GPS_TimeMS=524309800
GPS_Week=1832

The GPS time is the correct value of the flight, though I think the time is off by exactly one hour (Feb 21, 2015 1:38:29PM, flying in PST at 2:38 actually).

  1. Is there any correlation of TimeMS to the actual system time or GPS time?
  2. Is there a reliable offset of TimeMS or is it just a counter of time since power on?
  3. Is there a timezone associated with either time?
  4. Right now I have all default logging. Is there a log setting which would change this behavior?

Thanks for your help!

Jake
