Calendar view date filter works wrong

Question

We're using this API endpoint:
https://learn.microsoft.com/en-us/graph/api/user-list-calendarview?view=graph-rest-1.0&tabs=csharp#query-parameters

When we have parameters:

• startDateTime = 2022-08-12T00:00:00
• endDateTime = 2022-08-12T23:59:59

We recieve such things as

event1

• start 2022-08-11T00:00:00.000Z
• end 2022-08-12T00:00:00.000Z

event2

• start 2022-08-12T00:00:00.000Z
• end 2022-08-13T00:00:00.000Z

event3

• start 2022-08-13T00:00:00.000Z
• end 2022-08-14T00:00:00.000Z

Note, that event3 should not be there, but appears because was created in Amsterdam timezone.

• Go to outlook web
• Change your time zone in preferences to Amsterdam (UTC +1)
• Create all day events: yesterday, today, tomorrow
• Call API with parameters (GET /users/{id | userPrincipalName}/calendarView?startDateTime={start_datetime}&endDateTime={end_datetime})
• startDateTime : today 00:00:00
• endDateTime: today 23:59:59
• id: users id, that was used to create events in outlook
• Expected to recieve only todays event
• Actually you'll get today and tomorrow events.
