Morning Jeff, I have quoted my post from last night so all is in the same place.

The 20:15 is probably correct, certainly close. OSCAR said 20:23.
03:29 similar - OSCAR says 03:32
I went back to bed & started another session which OSCAR got & says ran from 03:35 to 06:06.
Full night including bathroom break)
I can say with certainty that it has not had any OTA firmware update. Attempts when I first bought the machine to connect it to the 'net were unsuccessful, from memory it wasn't possible because I wasn't in the USA. Bluetooth is turned off & it does not have access to the wifi here. I'm surprised to hear of a firmware update given that Devilbiss had ceased production/sales of these machines at the end of 2021. I'm not sure when OSCAR 1.4.0 was released, but I didn't update to it until mid November '22.
I have sent a copy of my SD Card to the dropbox as per your post. It is the same copy as that I took the screenshot of the timestamps in my previous post.
Folder renamed from DV64 to Cuppa.
Time zone here is UTC +10
I'll be back in touch tomorrow with more info hopefully
Regards
Cuppa
EDIT: In case it helps, the following from the DV64 Machine. Firmware Version V023RN20160118. BIOS Version V014BL20150630
I'm not sure what you will make of this but here goes:
First up this is what I did:
NOTE. Times were taken on the CPAP machines screen. They correspond with what is on my phone & laptop.
Commenced last nights(5/1/23) session at
21.39
Woke -> Switched off CPAP at
05.58-> Removed SD card & took a 'timestamp screenshot' of it's contents
-> Replaced SD card in CPAP at
06.07 for a 'workaround session' -> Switched CPAP off at
-> Removed SD card from CPAP & took another 'timestamp screenshot' of it's contents.
Both 'Timestamp' screenshots are in the pic below.
After this I uploaded my data to OSCAR. As expected it 'found' the workaround session from the 4/1/23 (done on morning of 5/1/23) , but not the one just done this morning (6/1/23).
NOTE. The first very brief session (44 seconds) shown on the night of 5/1/23 - Session 1672917962 can be ignored - my fault - a false start.
)
You will note that there is a discrepancy between the session start & finish times that are recorded in OSCAR & the times I took from the clock on the CPAP machine (
above in bold). Differences of up to around 12 minutes. Whilst that makes no sense whatsoever to me I believe the session durations to be correct. (Including the 'workaround one on 5/1/23 -Session #1672863022).
I will look forward to reading what you are able (or not able) to make of all this. If you need any additional info please ask.
Oh yes, when I uploaded my SD card to the dropbox last night I received an email confirmation I had done so. Didn't get that previously, but I think the difference was that this time I had signed into my Dropbox account. This one went to the 'Fred Bonjour' account. Previously it was sent to a different dropbox account.
