grrrr! The reason it was a non event is because people like me spent many, many hours going through millions of lines of code making sure it would be a non event!

_sigh_ that's what happens when you do your job too well




p.s. I think the intellipap gets its time from the data card. I don't think the machine changes time itself.

Yup they are good ol tanks that keep going and going. It's not a deal breaker. You just have to remember DST when reading your data. For me though, I believe my clock on tank was set in an Eastern time zone. It's always reads two hours later than my time zone. I don't normally hit the sack at 1 am on the following day....kind of skews the results don't ya think?

Said invalid date, data already exists for that date/time. Then set time to 23:55. OK. Then tried again to set date back to Nov 6 and got same error msg. Finally got fed up enough I took the SD card out and erased all data in the machine. Now I was able to reset date and time, now to Nov 7, 00:10. Reinserted SD card and it read data from it. Went to bed, got up about 7:30, and downloaded data to computer. Data for Nov 6 is now missing, but data for last night, Nov 7, is there.

I'm not sure what procedure one should follow to set time back one hour on the S9, but what I did ain't it!

UPDATE: I just looked at the summary data file on the card. When I reinserted the card into the S9 last night the machine erased all the data off the card because I had erased all the data off the machine.

So in case you weren't already aware, erasing data on the S9 erases machine memory AND SD data files.

I removed sd card, then erased data, re-inserted card, didn''t get erasing data screen, put sd card in puter and downloaded last nights data. Seems if you remove sd card before erasing data on S-9 you don't erase sd card. Sorry about your luck on that one, Idamtnboy, but thanks for the heads-up for me. john

Spent over 1/2 hour on tech support for my Q-see security system at work last spring to reset clock. Found out the hard drive has to be re-formatted to reset time. It has a 500 gig hard drive to store data, I have almost 3 months of it, and it needs re-formatted twice a year for clock to show correct time....... What the @$^*! john

Maybe we, as a group, should start a movement to stop this daylight savings time crapola. It's disturbing to sleep and restfulness, makes people accident prone for a few days after every time change, and it causes no end of grief (and needless cost) to our technology (witness the subject of this thread).

Let's just stay on ONE time, year round.

I did remove it first. That's what was so consternating. I expected the S9 to read the data off the card and reload it's own memory. That didn't happen! I also found I out I messed up and set the day one day too far. That's why Nov 6 data is missing. Now I had no choice but to erase the data again to reset the clock correctly. I have a back up of each card iteration and just copied them to another SD card so I could make changes and see what Resscan would show.

Since the machine date was wrong I was going to end up with two sets of Nov 7 data. I loaded the first Nov 7 data into Resscan, printed a report, and then deleted the session. Today I loaded last night's data into Resscan, which is dated Nov 7 again. Now I'm all set except that I have no Nov 6 data in Resscan.

I found out you cannot muck with the data on the SD card and then have Resscan read it. I used a hex editor to revise the data in the STR.edf to change the date from Nov 7 to Nov 6. That meant the CRC value was no longer the same even though I only changed two numbers by an increment of 1. Yep, you guessed it. Resscan checks the CRC and would not recognize the data. No way to fool Resscan into accepting data that wasn't generated on the S9. I have no idea what kind of algorithm is used to generate the CRC, and it's probably a state secret at Resmed. Heartening to know that at least one part of our medical info is pretty secure from tampering!

I used my EncoreView software to view last nights data. Surprise surprise, my clock was correct. My guess is that plugging the data card into the reader reset the clock to the systems clock on my computer. Interesting, thought I would share this with those that have an M series machine.

My betamax is flashing 12:00..............what do I know! john

What I like are the radios that were purchased during the old DST law. Now the radios need to be reset 4 times a year.

As for the CPAP, it can just be off by what it is off. All I want to see is the total time and events.

The states that do NOT have DST have the right idea!
It wastes resources and kills people.

ppharman - It looks like my PR System One did the same thing. They are both Respironics machines so that seems likely. The same thing happened with my M Series.

I have been gathering data with software for over 2 years now and have never changed the time on my cpap machine but my data was always at the current correct time.

I thinks what ppharman said is what happens.

I have two clock radios that get a time signal by way of the power grid. I have no idea whether my xpaps can do the same.

BTW, the clock radios do NOT change to / from DST on the dates that are currently used for the time change. It seems the power grid follows the old schedule.

Anyone know if answering yes to that prompt really erases the data?

Hi Muse!

Didn't you know that nobody needs their data after the time change? My guess is the one department designed the data side of the system and another the non-technical such as the clock and the two departments never talk. LOL
