gettimeofday() still useless across a deep sleep

[eyaleb]

As I am collecting temperature related data I looked at the fixed gettimeofday(). It does much better than before, and so far I get very good time tracking from it, so I am now looking at the relationship between TSENS and gettimeofday().

I have three modules, and I see a reasonably constant (but different) error rate for all. I am now moving the modules between rooms with different temperature and let it run for a few days. I will then vary the deep sleep period and see how well we track time.

Not so exciting but needed to be done.
