Dates and datetimes
All dates and datetimes provided by the API are in
ISO 8601 format. In case
the date is in UTC, it follows the following formats:
- Dates: YYYY-MM-DD, 2016-04-28
Date times YYYY-MM-DDThh:mm:ssZ, 2016-02-16T05:03:57Z
As the local time plays an important role in sleep and activity data, we often
expose local times in the API using standrad ISO 8601 notation. For example
the above date time is shown in Pacific Standard Time as
Date times YYYY-MM-DDThh:mm:ss+ZZ:ZZ,
Durations as seconds
We express all durations as seconds. For example amount of REM sleep per night
is expressed in seconds.
Classification arrays as strings
Both activity and sleep data contain interval classifications. We have used a
string instead of a list to encode phases for a more compact representation.
