Just a thought. When I review my tlog or my APM log I notice the time is related to zero and marches out to the right in time in seconds. Although this is nice I would like to see times in the time zone you are flying in with Date and Time (HH:MM:SS). Is there currently anyway to make this happen? Does the GPS pickup Date and Time for where your located and port that into the log?
dataflash logs don't contain enough info for this.
You can post your ideas on github where the code changes occur.
