Change the Time in ResMed 11 machine

Just wondering if I can change the time on my ResMed Air Sense 11?

When I download the data to Sleep HQ, I notice the time is off around 2-3 hours. When I go into the menu in the machine, it said I can't change the time because the machine already have data. So it's like I need to delete the data first, which I can't, meaning I have to keep that for my doctor/insurance purposes.

This makes me think perhaps the time was set when it was manufactured, or maybe at another state when it was delivered to the vendor, etc.

Is there another way to change the time on the machine?

No...there is no other way to try to reset the time on the AirSense/AirCurve 11 machines without erasing past data.
Past model machines like the AirSense/AirCurve 10 machines had a clock you could actually set easily.
ResMed didn't include a clock like that with the 11 series models.

There is a little trick we can do if using OSCAR and the time is off but I have no idea if you can do anything with SleepHQ like we can with OSCAR.
