Somnopose data in OSCAR (time shift)
Somnopose data in OSCAR (time shift)
Somnopose data is time shifted when into OSCAR.
The shift amount corresponds to my time zone EDT (-5 hours from Greenwich).

I am using Somnopose to: (a)  track sleep position and then (b) import the data into OCSAR
This same problem was experienced with Sleepyhead but at the time I was feeling much better and did not pursue it and put Somnopose aside. Since then I have had a big relapse into super fatigue and will be upgrading to a BiLEVEL any day now. This motivates me to pursue the possibility of positional factors. 
The developer of Somnopose is said to be available and responsive but I have decided to ask the question here first. The local time is included in the data file so time zone is being accounted for at some level.




OSCAR: MacBook Pro, MacOS 10.14.6, 16Gb
Somnopose: iPhone 5SE, IOS 13.1 beta
Data from Somnopose export email and attached CSV file
(Email text sent by Somnopose export)

SomnoPose 2.0
Device name: G&MB-SE
Data start time: Aug 30, 2019 at 00:02:34 Eastern Daylight Time
Data end time:  Aug 30, 2019 at 07:36:05 Eastern Daylight Time
Data time span (start to end):      ‣7:33:31
Recorded data time (excluding gaps): ‣7:33:27
Number of samples: 13687                    

DATA COLUMNS IN ATTACHMENT                    

Timestamp: Time and date of the data sample (as seconds since the first instant of 1 January 2001, GMT)                    

Orientation: Sleep position, represented by side-to-side angle of the device in degrees, -180 to 180. Zero for face up, positive values for facing right, negative values for facing left.                    

Inclination: Upright angle of the device (and user) in degrees, 0 to 180. Zero for an upright position (e.g., user standing), 90 for a horizonal position (user lying down), 180 for the unlikely upside-down situation.                   

Time_of_day: Time of the data sample as hours, minutes, and seconds, derived from the Timestamp value, using the device's time zone setting. It gives no additional information, but is provided in a human-readable format for convenient reference.                    

Date: Date of the data sample as year, month and day, derived from the Timestamp value. It gives no additional information, but is provided in a human-readable format for convenient reference. To reduce file size, this is not included on every line.

(Several of first lines in CSV file)

RE: Somnopose data in OSCAR (time shift)
I was unaware that anybody still used the Somnopose or that it had a time problem.
It is likely that it is the same problem the oximetry data had, so I will look into that and get it fixed for the next release.

Thanks for letting us know.
