time axis of graphs in Oscar

time axis of graphs in Oscar
Hello Apnea Board Forum,

I am not sure which thread ia to add this question.

I have a ResMed S 10 auto.

With Oscar 1.3.1, the plots of my CPAP parameters versus a time are errantly shifted by about 2 hours.  When it shows 12:40 AM, it should be 10:35 PM.  I account for 5 minutes of ramp time.
 
Since ResScan makes the same mistake, the SDHC card must be wrong, which implies the ResMed machine writes the wrong data.  How can I find the ResMed time, and fix it?  Alternatively, can I do the offset in Oscar and ResMed?

Note, I mainly use Oscar, but ResMed shows the length of each separate CA event, which I need.

A two hour offset might be due to daylight savings time, or time zone.  I suspect the ResMed time is updated through the airwaves.

I would appreciate any ideas you have.

Thank you,
mjrPdqkLguUgGLE

RE: time axis of graphs in Oscar
This is the best forum to post your question.

OSCAR does show the time of each separate CA event. To see a list of events, click on the Events tab on the Daily page.

OSCAR and ResScan both report the time as recorded by the CPAP machine.  You can set the time on your ResMed AirSense 10 machine in the clinical settings menu.

ResMed does not update your machine's clock over the air. 

I suggest you update your profile on ApneaBoard to reflect your current CPAP machine use. Click on UserCP at the top right of the page, then on Edit Profile.
