Double check on that on your own machine, please. Unless it's a recent change, I don't think you can change the date or time without a special cable adapter and software.
It would be a great thing if Philips has fixed this. If so, let us know what machine and firmware version you have.
1) PRS1 has better DC power capabilities. ResMed requires an expensive DC-DC converter, not just DC power.
2) The official ResScan software is enormously superior to the Encore software. Encore doesn't allow you to zoom in on airflow waveforms, you can only see a tiny, all night report of airflow. ResScan lets you zoom, and shows other info like flow limitation, minute vent, leaks, etc. in a better minute by minute graph. However, SleepyHead works for both, and is superior to both in many ways for the home user.
3) The PRS1 display is a crime. It's terribly hard to read, and there's no way to make it light up at night without turning the machine off, so you can't check what pressure it's at without a flashlight or turning on the room light. I find it really hard to read by a flashlight because it's got a limited viewing angle and the light has to come in at the right angle.
4) Reports from many users on internet forums indicate that the ResMed pressure control feels better to many people. The ResMed feels "smooth" while the PRS1 feels like it "puffs." This seems to be both with and without EPR/Flex.
5) The ResMed FOT technique seems to work better than Philips's pressure pulse at detecting central apneas. The PRS1 pressure pulse disturbs some people.
I have both PRS1 Auto and S9 AutoSet. I find myself slightly preferring the AutoSet. It feels better somehow, both in terms of ease of use, "slickness," and the feel of the air.
The PRS1 seems a little tougher. The S9 seems more modern and "agile."
If I were buying a new one, It would be roughly a tossup to me.
