Summary: changed LI-7550/LI-7700 time to be synchronized, set LI-7700 washer settings

When we arrived they were rolling the fields and there was tons of dust in the air, as there was a strong breeze. RSSI on the LI-7700 was down to 10 from all the dust. We waiting until the tractor seemed like it was done passing through the field and cleaned the mirrors so that RSSI was up to 62.

Checked the data and no data was recorded for the LI-7700 due to time synchronization issues. Changed the time settings in the LI-7500 to 'Automatic' and 'Pacific Standard Time'. Changed the time settings in the LI-7700 to 'Slave' to run off of the LI-7550 clock. System was recording all the data when we left.

Also changed the washer settings in the LI-7700, as these were off. Set to was when RSSI hits 20%, re-check every 3 hours, with spray duration of 20 seconds from 1:00 to 23:00 each day. Mirror heater settings are to 2C above ambient using 7% of power from 22:00 to 6:00 each day.
