Summary: calibrated 7700, and normal data download, clock problems with LI-7700

We arrived about 1:30. It was cool, cloudy and rainy. Something was wrong with the Licor GHG system. We could not initially connect to the 7700. After connecting to the 7550 we could connect to the 7700, but its clock was set to the default 1970 time. We reset the clock and all seemed well. We calibrated the 7700. The 7550 clock was a little slow. At 12:32 I reset it from 12:20.

Looking at the data, on day 267 at about 5:51 something happened that caused the 7700 clock to reset and the 7550 started to skip taking 10sec of 20Hz data then skipping 10secs.
