set current time

[towbarron]

How would I set the time on my Remstar A flex to current time, when I use the Sleepyhead it seem like I am a half hour out of sync, between the sleepyhead program and my Cpap machine ?

[RandyJ]

Is the time on your computer correct?

[Goofproof]

Xpaps arent clocks, they have a system clock built in as a reference, set to gmt. Their is no simple adjustment and they do not maintain accurate time, a Timex from wallmart keeps time.

The time from your xpap is comverted in your computer, so you can get a fudge by setting your computer wrong to fool it. Jim

For me not worth the trouble, time is not relative, I know when I go to bedand get up, the data telled me what happened in that time frame.

[towbarron]

Ok, I will just deal with it as it I, not worth the effort. Just thought that it might be something simple

Is the time on your machine "slow" to what the sleepyhead program shows?
How long have you had it?
Was it new when you got it?
Which model is it?
Respironics (and Philips/Respironics) has been making an "A-Flex" model since about 2007.
Some of the earliest "System One" models (early 2010) had a firmware version that allowed for changing time in them.

Otherwise, for many, many years and generations of these machines have had a bad characteristic of losing about 2 minutes of time on their internal clocks per month. And, typically it takes an expensive cable and software to reset the clock. Some DMEs may be able to do that for you.

Den,
Just curious: Do all PRS1 family xPAP's since 2010 now have an admin-settable clock?

It is possible to sync the S9 in the admin controls without special gear. I've been able to synchronize it to my "SkyScan" atomic clock. My S9 loses about 10 seconds every two weeks. It also burps and skips some data on days when DLS time changes forward. I'll have more data to confirm in the future. Still, it's nice to be able to sync the oximeter to the atomic clock and know the times are going to be fairly close. I remember my old M-Series Pro had no admin time setting.

It would be nice to have more precise chronometry with DLS settings tweaks on our CPAP's - maybe even atomic clock sync. Maybe for PRS2 and S10?

No, they "fixed" that feature in future firmware levels after that (as I understand it). Traditionally, the Respironics (and more recent PR machines) have all been set to Greenwich Mean Time and then the Encore software adjusts the local time by the timezone in the computer. However, like I stated, the previous generations of machines (Legacy and M Series) all had that nasty habit of losing time (one - two minutes per month)........even with a NEW battery in them. A few years ago, I managed to acquire the (expensive) cable and software for setting the time in mine......which came in handy when I acquired a ("never used") Pro 2 from the CPAPAuction site which had a dead battery and broken hose nipple inside the machine.
It would have been a great feature if they would have designed an externally replaceable battery and the capabilities of setting the internal clocks on these things. I figured out that the battery holders on computer motherboards have "legs" that fit exactly into solder holes in the CPAP motherboard (PCA), so, I un-soldered the dead one in that machine and soldered in a battery holder from one of my old computer motherboards.......so I can now use easily replaceable CR2032 batteries instead of the special BR2032 they soldered in them. You still have to have the special cable and software, but now it's very easy to keep these thing running longer.

For a very short time the first PR S1 machines allowed for GMT time offset...like hours.
The one that I saw didn't let me set it like a regular clock though...just plus or minus however many hours I was off from GMT time.
Not a real clock...at least in the one I saw.
Respironics didn't continue with the GMT offset setting...subsequent models had that feature omitted.

So there is no easy way to alter the internal clock on any Respironics machine (new or old).
Though I haven't seen much of a error in time with my PR S1 750 which has been in use since Nov 2011.
It says I woke up at 4:43 this morning and that's probably within 5 minutes.
I will try to remember to check it carefully tomorrow.

It's odd that a relatively new PR S1 machine would be off by so much as 30 minutes or more.

Respironics screws their customers this way. The patient can't fix the clock if it's off. The clock battery is not customer replaceable. A proprietary cable and software not available to the general public are required to set the clock. I suspect that most DMEs can't even fix the time without sending it back to the factory or a service center.

It's all moot as XPAPS aren't clocks, they are medical devices designed to help splint the airway open so you can breath. Clock time doesn't force your airway open, the clock is just in it to run the limited computer that controls the machine, what counts is the time your airway is blocked and the number of times it happens. Jim

Contact Rollex, maybe they can install one that will keep time, I doubt if INS will pay for the upgrade.

Someone pointed out to me that SleepyHead has a clock drift feature in the upper top right side of the Preferences/CPAP tab.
It lets you alter the time set to some extent. I have not experimented with it yet to see if it will fix the issue with the reports being slightly off.
Apparently it lets you adjust so that you can match up to the computer clock.
Don't know if it will work or not. Haven't had a chance to experiment with it.

I tried the drift offset and it works. I started my CPAP at 11:00 according to my cell phone's system time. Sleepyhead showed beginning of session at 11:08. So I had to correct by 480 seconds. I typed in -480 and my graphs all shifted over to show starting time of 11:00. Now the times on the cardiac monitor I am on for 2 weeks will be better coordinated. Thanks for the pointer.

It's a medical device that is designed to treat apnea and collect data to aid in managing your treatment.

If the clock is off, the data produced is somewhat incorrect and impairs your ability to manage your treatment.

If you're trying to figure out why you woke up choking at 1 AM last night, it's nice if the data flags the associated events as 1 AM instead of 1:30 AM.

I was going to try out the drift time set thing in SleepyHead...so I made special note to check clock when I got up this morning.
Would you believe it that the machine time was spot on to my clock time?
Anyway...someone else has already posted that they tried it and it works so there is a way to work around the time drift on the PR S1 machines.
I never knew that little feature existed till the other day when someone asked me about it.

On my S9 machine, I think that the data gets chopped off a bit on the start or end of a session, so experiment a bit with how you calibrate the time drift. Do something like run it for a minute or two, then take hold your breath at some known clock time.
