S9vpap usage time

[Iceracer]

Hi all

I'm a little confused when I woke up this
Morning I check my vpap for usage , mask
Leak And Ahi like I do every morning . For some
Reason it said I used it for 11 hours ! I wasn't in bed for
More then 6 hrs ( never am due to severe osteo
Arthritis and A.S an autoimmune disease ) when I downloaded
Into sleepyhead usage was 4:59 hours and rescan was 5:56
Why the difference ? Sleepyhead is correct Rescan data
Goes till 4:59 and then data is blank ! Any thoughts or ideas ?
I'm going to my respiratory therapist this
Week and want to be able to tell him what's going on !

Sleepyhead and Rescan handle the splicing of two sessions in the same day differently.
Check to see if you system clock is set correctly. The day starts and ends when the system clock says 12:00 (noon).

1) is the clock correct, and
2) did you sleep more than once in a 24 hour period between whenever the clock in your unit thinks noon is?
