Obvious to me: the reticence of SleepHQ developers to address the issue
of time zones is a desire to prevent patients from seeking help or advice
from online forums as this one. How are you unable to see this?
Sometimes I wonder how you survive with such a warped view of the world.
Explain to me exactly how the timezone issue prevents people using forums such as this one. The exact same problem occurs on Nicko's Facebook forum. If he was using the TZ as a means of keeping people on his own forum, don't you think he would fix the problem there?
The real answer is that they set it up this way without foreseeing the difficulties and now it's difficult to change without spending time and money recoding part of the system. At the same time they're trying to deliver long-promised updates and the TZ issue is not a high priority for Nicko and Adam, despite my prompting.
I personally think the time zone issue is one of
sloppy programming decisions rather than some malevolent attempt at preventing patients from seeking help/advice from on line forums.
The very fact that SleepHQ is set up so the patient can easily share a link to the actual
data on an anonymous platform so that anybody with the link can not only access that data, but also analyze it by zooming in and scrolling through it, points to a genuine desire to help patients get help from forums like this one.
That said, it ought to be reasonably easy to at least add a field in the SleepyHQ report for "Patient's Time Zone" that that tells anybody looking at the data what time zone the patient is in so that they can properly deduce the correct local time for the patient.
And having said that, I also wonder something about how Resmed machines actually timestamp their data: Do they use local time from the machine's settings or GMT (calculated from local time, perhaps?) to time stamp the data?
I know that PR machines up through and including the DreamStation 1 time stamp the actual data on the card with the machine's notion of what time it is in GMT. And to view the data in Encore Pro you have to enter a local time zone. (Encore Pro is the PR software for viewing data on machines up to and including the DreamStation 1.) However, the battery responsible for maintaining the internal clock
cannot be reset and the clocks are known to drift away from GMT at unpredictable rates. (My 2016 PR DreamStation BiPAP Auto's clock currently needs an offset of -1:13:50 in Oscar/SleepyHead whereas my husband's 2014 PR System One (Series 60) Auto's clock currently needs an offset of +32:06.) You can't fix the clock drift if you are using Encore Pro to look at the data.
I also know that you have to set the local time (correctly) when you first set up a Resmed machine. (And adjustments to that time have to be done carefully, as
Miss Emitra found out the hard way. So the question is: Does Resmed use the machine's local time setting to create the timestamps on the data? Or does it do something else? When I set up the AirCurve 10 that I'm borrowing from Pugsy, I don't recall a "time zone" setting on the AirCurve, but I did have to set the local time correctly in order to get the time stamps on the data to show up correctly.
So it's not clear to me what decisions were made by SleepHQ's programmers that led to using the
viewer's time zone when looking at time stamped data in the daily data part of the web application.
