Goal: retrieve list of completed To Dos of a users for a given day.
The description of completedDateTime states that it refers to the timezone specified (link to doc). However it appears that the returned date value is always UTC midnight
Repo: I created and completed a test todo with the official Microsoft To Do app today on September 27th with my device set to "Denver - Standard Mountain Time" (local time 1 AM). When I list the todos via the API and specify the header "Prefer: outlook.timezone='America/Denver'", it returns:
"timeZone": "Mountain Standard Time"
This is not correct. I completed the todo on September 27th - not September 26th.
What am I doing wrong?
