RE: Setting time and date on Resmed Airsense 10
A better way to set the clock back
As people have noted, you sometimes can't set the Resmed CPAP Autoset 10 (and similar machines) clock (date, hour, minute) back. This messes people up because of daylight savings time, or time zone changes, and especially if you accidentally set the clock a day or two too far ahead. Apparently it won't let you set the time back before the last data present on the SD Card flash drive.
Some people here have suggested backing up the SD card, erasing compliance data (for which you need to get into the clinical settings menu - discussed elsewhere; but you need to do that to set the clock anyway), then setting the time right, and restoring data to the SD card.
But a DME, insurance company, employer, government agency, etc., might for various reasons want to verify that the data on your SD card is authentic, and not fraudulent. Aside from the fact that Apple and modern Microsoft Windows computers add potentially troublesome files to the card if it isn't write protected, that procedure will probably leave traces of being externally modified. E.g., as others have noted, the Journal.dat file is supposed to be in a particular physical location on the card, and there are other less obvious ways to hide information on SD cards or inside the CPAP machine. (BTW, some people say here Journal.dat is zero filled - but not on MY Airsense Autoset 10. Also, the file is hidden, my Windows machine calls it protected, so I need to change default view characteristics to see it is there.)
So it is better to just change the time in steps. Just BEFORE (NOT AFTER) you start using it for the night, change the date & time. If it can be set to the correct time, you are done.
If not, set the minutes right, then set the hours back as far as it lets you. Repeat setting the hours back as far as it lets on on succeeding nights, until the date and time are right.
Of course the data still looks weird - it looks like you slept a LOT for those days - perhaps almost all day. If you don't want that, set it back only a few hours a day until you have the right time.
Make a note of these changes, so you can justify changing the time if needed. It is entirely possible that time settings show up in the forensic data written to the card, or is obvious from the data sent to Resmed. If using OSCAR or SleepyHead, you may could also add comments for that day so you won't be confused.
If you have a separate oximeter with a clock in it, always set its time the same, so sleep and oximetry data will be synced, and make note of that too.
At least that is my 2 cents.
