ResMed Time Issues
04-06-2012, 10:22 PM
Since daylight savings began, I've noticed my unit has an on again, off again problem where it calculates my AHI based on exactly two times the number of hours I've actually sleeped. That, and every now and then it figures I slept roughly 500+ hours per night. Yyyyyeah. Okay.
Anyone else have such a problem?

Is this the machine reporting it or the software (rescan or sleepyhead) that is doing it?

B36, JumpStart, and Steven gave some suggestions about the S9 daylight saving in this thread.

This is a known bug, which JediMark is aware of, triggered by the DST change. There is a workaround to use until the bug is fixed.
Open SleepyHead, select Daily. In the bottom left panel (the one with the colors), with the tab of Details, scroll to the bottom. Under Session Information, you will see at least two different time periods, sometimes more, (eg,if you left your machine to go to the bathroom, etc., during the night). Look in the column denominated as On. Select the icon for the session or sessions which are not accurate in that column, and click to turn the right hand side (left is black) from green to red. This will remove that information from your statistics, and SleepyHead will work correctly.
Hope this helps.

The Original Poster (Crippiter) doesn't use SleepyHead, Crippiter uses ResScan....
So, this is an issue due to a bug within the S9 firmware, I think (not due to a SleepyHead or ResScan bug), (I think).
From this thread, b360155 reported this:

My usage hours were off by an hour as far as start and stop times last night with both software and the clock did not change on my machine. Sleepyhead said I went to sleep last night at 9:41 PM and woke up this morning at 4:02 AM. ResScan said that I went to sleep last night at 9:41 PM and woke up this morning at 4:03 AM. In truth, I went to sleep at 10:41 PM and woke up at 5:03 AM. Interestingly, the summary graphs with both software show the same range of usage and same total usage hours. But on the detailed daily graphs, ResScan has a gap with no data showing up between 2:00 and 3:00 AM. Sleepyhead shows continuous data throughout the evening.
