Usage Explanation

NOTE - I edited this because a future PR will move the setting into General Settings to update the soon-to-be added Treatment tables and Statistics charts. I'll be grabbing these words as a first draft for the LoopFollowDocs updates.

In the LoopFollow Settings, chose General Settings and tap on Time Zone Override.

• You set the time zone to that where the PWD lives and then the caregiver can travel without having the LF plot change to the caregivers current tz
  • It is easiest to do this the first time while in the same time zone; initially the current tz is the default
  • But any time zone can be manually selected, so if you forget, this can be done while on travel
• The selection for the tz of the PWD user is remembered
• Conversely, if the PWD is on travel, the tz can be adjusted to their current tz
• If the PWD and caregiver happen to be traveling together, then the caregiver can just switch off the Time Zone Override for that joint trip

Configuration

Start with dev on the LoopFollow phone, iPhone 8 running iOS16

• I am using this phone because I am not running any other tests on it
• Changing automatic time will not cause an issue on this test phone
• Please - any phone which is running an OS-AID (for real) should never modify time zone away from automatic

For later testing, update to code this PR for that same phone.

Common Timezone

Configure so LoopFollow phone follows a Loop URL with both phones in the same timezone.

• Observe that LF plot aligns with Loop time zone
• The Loop phone is in UTC -8

Timezone more negative wrt UTC

Modify the LF phone to be in a different timezone

• change timezone to be UTC-10
  • observe LF plot time shifted as well
• rebuild with code from this PR
  • must go into settings, graph settings, TimeZone Override and must select the desired timezone for the Loop (or Trio) phone
  • Selected US Pacific Time (UTC-8), LF phone is on Honolulu time (UTC-10
  • LF home plot shows the home time zone of UTC-8

Timezone more positive wrt UTC

Modify the LF phone to be in a different timezone

• change timezone to be UTC+1 (Stockholm)
  • The Time Zone Offset remains configured for US Pacific Time (UTC-8)
  • LF home plot shows the home time zone of UTC-8
  • Disable Time Zone Offset, LF plot shows UTC+1 on the plot
  • Enable Time Zone Offset again - it remembers the previous setting for US Pacific Time
  • LF plot returns to UTC-8 plot

Repeat with a Trio URL

similar success

I pushed a linting change from when I built this branch.
The version with the linting change is the one that was tested.
