I was having a look at the timestamp field values in accel_walking_outbound.json.items, it is not making sense to me. For example, the value are 5913.578209625, 5913.588205625 etc. How to interpret these values? Why a decimal point? Thanks.

That is correct. The time should be (at least all observations I have seen) equally spaced. Theres is no assumption of the data being sorted however. That is, a series of timestamps t1, t2, t3,...tn could be reported in the order t1,t3,t2...
Are you saying the values are approximately 10ms between observations?
Hi Avinash: The timestamps is the relative time since an arbitrary start point (in practice it is the time since the device was restarted in seconds). If you subtract the first timestamp in the series from each timestamp you get the relative time in the activity.
