That would > account for (I think) 13 seconds (or is it 14 now that we've had a > leapsecond?). That's it! Infact, it is apparent if one looks on the webpage: Receiver Time: 2006-08-30T20:26:30.0 GPS Local Time: 2006-08-30T22:26:19 Local Time is UTC + 2h, so there you have 2006-08-30T20:26:19 actually, and infact this shows that ISO2 isn't following the ISO format. Now, with 14 seconds of GPS/UTC offset the receiver Time should be 2006-08-T20:26:16 and the remaining difference of 3 seconds is maybe due to the report-time??? I think it is much better to do the :SYST:TIME? to get the time, while all the other stuff very well may come out of the :SYST:STAT? report and parsing. Ideally it should read out the UTC-GPS time-difference and compensate with that OR set it to UTC. Yes, I know I can add commands to the end of my conf-file. UTC is better, since then it would handle leap-seconds +/- too early leap- second announcements and the leap-second bug.
