We have been experiencing some receiver problems lately.

Day 030 and Day 032 show significant jumps in the pseudoranges and phase
values.  It appears to be a receiver event - possibly the receiver reset
its system time without resetting its time tag.

These events occur on day 030 at 05:44:30 to 05:56:00 and on day 032 at
22:09:30 to 22:14:00.  

Day 031 is okay.  We have no data for day 033 due to receiver failure.
Day 034 exceeds the 1 millisecond requirement for the time tag for a
portion of the day.
