Editing session start/end times within OSCAR
#1
Question 
Editing session start/end times within OSCAR
Can OSCAR 1.2.0 session start and end times be edited within OSCAR? I'm talking about the very first and last times that are used to compute total duration time. Daylight Saving Time (DST) has caused a one hour mismatch between my Oximeter (Wellue O2Ring) and my Airsense 10 data stored in OSCAR. Although I have corrected my Airsense 10 clock after the fact the data stored in OSCAR is incorrect for two days.  The clock correction will only effect future SD card data recordings. But now I'm left with two days of non-synced data in OSCAR.

RE: Editing session start/end times within OSCAR
You can purge the data for the dates in error and re-import. During import is possible to apply a clock drift offset in File/Preferences/CPAP. You might be able to play with that to import data with a corrected timestamp. You can purge and re-import until you get what you want. There is no capability to edit times in Oscar.

RE: Editing session start/end times within OSCAR
Sleeprider, thanks for replying. I'm still confused. The first data I import each day is data recorded on the SD card. I don't believe the Airsense 10 can re-record this data. Please help!

jas102543 - SR said re-import  not rerecord.

Here are the steps:
  1. Open the Daily screen on the day with the wrong time.
  2. Make note of the start time and how much you need to change it.
  3. Go to Data > Advanced > Purge Current Selected Day.
  4. Go to File > Preferences > CPAP and enter the time difference.  Note: positive numbers to move the data ahead in time and use negative values to go back in time.
  5. Go to the Welcome screen and select CPAP Importer (re-import).
  6. Your data should now be the correct time.
  7. Remember to go back to  File > Preferences > CPAP and set it back to all zeros.

Red,
I followed your 7-step instructions.  Everything proceeded as expected until I performed step 7, at which time the graphs for the session returned to displaying the wrong time.  Do you have any suggestions as to what I might be doing incorrectly?
Thanks,
Jim

RE: Editing session start/end times within OSCAR
This setting is global.  You asked about that day.  I was listing how to view that day only.  Otherwise, all other times will be incorrect by the amount offset that you enter. The time of your sleep sessions is not important. It's the total time that you were using the CPAP that's important.

Red,
Thanks for the clarification.  I was thinking the time adjustment only was applied during data input using the CPAP Importer.
