Re: [sensors] Does SensorReading always need a timeStamp ?

This is an interesting problem.  There are all kinds of sensors, and 
thus a number of different reporting styles.  In some cases it's 
important to relate the event to a real time - we want to know that 
this reading was taken at 8:02 AM locally, which means we want to know
 the timezone/DST situation as well.  In some other cases the 
interesting data is the relative time to other captures - here we 
don't want tz/dst, and we don't want to be affected by any possible 
time changes on the device. Think of these as Realtime Clock vs. 
Monitonic Clock.  And I can imagine in some cases, we may not care at 
all about the time - that's the original subject of this issue.  In 
general, the situation is more determined by the sensor in question 
than the application talking to it. Can there be a way to express the 
time in a flexible way such that the sensor can choose any of these 
three as their preferred reporting style?
