It looks like Glooko/Dexcom are broken. The UTC time here is (at the moment of typing) “Mon Oct 15 04:37:27 UTC 2018”, the local time is (at the moment of typing) “Sun Oct 14 21:38:55 PDT 2018”; i.e. I am 7 hours behind UTC.
Glooko reports three separate syncs (all changed to 24 hour format):
Omnipod: 21:11 on the 14th
Dexcom account: 23:59 on the 14th
Dexcom G6: 03:48 on the 15th
The Decom web site reports the last uploaded G6 reading at 20:48 on the 14th, so this is the standard computer programmer time zone incompetence. These days that is not forgivable.
Nevertheless, despite that really big error the “graph” display in Glooko appears to have the timezone correct, which makes me wonder what will happen when I go to the UK (8 hours ahead) or Taiwan (16 hours ahead). I’m probably going to give up and change both devices to UTC, I am getting totally fed up with the unnecessary Omnipod PDM failures when I take a transatlantic or transpacific flight.
Other displays in Glooko have the CGM time zone clearly wrong; graphs/calendar is showing readings at midnight from the CGM (as I type it is 10:03PM) while the Omnipod readings stop at about 9PM (that is “correct”, assuming you believe that local time can ever be correct.)
I tried to find the CGM data in the Glooko log book. I can’t find it; the Omnipod readings are all there, the log book asserts it is showing both, but it is clearly not doing so.
As of this point my conclusion is that Glooko is useless; the next step is to find out how to get this data into an Excel spread sheet.
