Rewinding time breaks graphs

[saercnap]

I traveled backwards in timezones recently but just fixed the clock.

The time on the dexcom was ~8pm but local time was ~1pm. After fixing the clock and downloading the graph display goes to 8pm with a large gap in display. New (clock change forward) entries don't seem to be rendered properly.

Can the receiver time be used with a runtime-gathered offset rather than relying on displaytime?

Planning an upgrade to Dexcom driver at some point in the future that will bring this. I don't feel like it's imminent, though. Are you able to compensate at present?

Sounds fine provided too many don't get caught in the same position as the android-uploader timezone problems. I'll manage for now

It's now posting with system tz to Mongolab. Internally it's still relying on an integer timestamp. Small steps.

0f26ed1 will keep this from being as big a problem too.
