If you travel over the international date line, you will really mess up the machine because the clock is there to record compliance, not for you to use as an alarm clock...stop it! Choose a home time zone and leave it alone.
To get the time back, try changing 1-hour at a time. Moving time back may be easier than forward. I believe several have found resetting the data can allow a large time-change.
Well I guess I was wrong to do it, and won't do it again.
My reason for doing it was that I am on a one month trip to Asia and the time was set to Honolulu. The result of that was that the Sleep Report each morning claimed that I had only used the machine about 5:30 when in reality I had used it 8:00 or 9:00 hours. I think that this was caused by the fact that whenever the machine considers that a new day has started it is in the middle of my sleep period. In the expanded data visible when the Essentials is set to Plus it does show the the used about right. So I think that the expanded sleep report is consolidating the data from part of two different sleep periods rather than one "night".
So my (probably very wrong I see now) idea was to set the clock to the real time and date where I am and will be for the next month on the theory that it would make my Sleep Reports more accurate by corresponding to my real individual night's sleep and not a composite of two partial nights.
Bottom Line: I won't do it anymore.
Now the issue is how to get it back to the correct date and time where the machine was set up and to where I will return after a couple of weeks more.
When I originally tried to set the clock back (the simplest way to think of the time at my present location is that it is 6 hours behind and one day ahead of Honolulu time), I tried to set the clock back 6 hours and got an error message that you can't set the time in the past. So then I tried first setting the day ahead one day, which worked. I though the the machine would recognize that the day was in the future and let me set the time. Wrong.
So now the date is one day ahead and the time is ahead of the actual time on that date anywhere.
As a further complication the machine cannot transmit my daily sleep studies to myAir since the US and Canadian Based Machines use CDMA while machines sold everywhere else in the world use GSM.
My next mistake was to imagine that once I returned to Honolulu all my data from the past month would be transmitted at once, and maybe even the date would fix itself.
However today I spoke with a "Faiz" at ResMed support and he claims that the machine only transmits the date for the previous night, and when it can't do that, it gives up but their backup plan is that the machine has been saving the data all along to the SD Card. That is fine except that when I got the machine there was no SD Card in it as there was supposed to be. So according to Faiz all my data for the past month will be lost when I get back to Honolulu, and it
will only transmit data from when I get there one day at a time. So since I was not supplied with an SD Card I guess all I can do for the present is to write down the sleep report data from the screen of the device on a paper each morning which is better than nothing.
Do you agree that what Faiz said is true based on your experience?
What is still unclear even if that is correct, is that in the Essentials Plus Menu I can change the period from 1 day (where I have it now so I can write down the daily statistics) to 1 week or one month etc. So this leads m to believe that even if the machine won't (Faiz says) transmit data older than one day, the data from previous days is there in the machine and if I get an SD Card maybe it would be copied to the card and not lost?
Then as far as correcting the date back to the real date in Honolulu, it appears that the only way to do that is to erase all data from the Configuration Menu and then maybe it can be set to to the correct local date and time. Do you agree that this is the only way to correct the date?
Thanks for any advice and help you would be willing to provide.
