Timestamps can be inconsistent between sent and received data

[kh90909]

This happens when the local PC time does not match the Particle Cloud server time. Received data generally contains a timestamp from the cloud (which is used for the terminal timestamp), but sent data does not, so the local PC time is used for the timestamp.

Possible solutions / workarounds:

• Use local PC time for all timestamps
• Estimate the difference between the local time and the cloud time and apply a correction factor
• Request that Particle include a timestamp in the responses for calling functions and publishing events
