o2ring data date is off by a day from cpap data

[jhummell]

I have an aircurve 10 Vauto, and an wellue o2Ring.
I imported my AirCurve using the SD card.   Also used O2 Insight Pro.
When I used OSCAR 1.3.1 Data -> Import Viatom/Wellue Data my O2 data came in a day off of the AirCurve cpap data.

When I import from my SD card it goes into my data the day I'm importing i.e. 27 is the night of the 26 through the 27.
Buy the O2 data date is the begging of the night date the 26th.  Even though it also runs from the 26 through the 27th.

How do I shift my data so it all lines up?

Check the date setting in your VAuto. It sounds like it might be set a day in advance.

26 should be from noon on the 26th to noon on the 27th. The date and time are taken from the data recorded on the SD card. It doesn't matter when you import it.
