UpdateMeeting API end_date_time format with milliseconds

I need a confirmation that updateMeeting API does/does not support date time format with milliseconds.

Today I noticed when I am using updateMeeting API to update a recurrence meeting’s end date, it does not work. After an investigation, i fount out that we are using date format “2020-06-28T23:30:00.000Z” for end_date_time field inside recurrence info, which includes the milliseconds.

After I manually removed milliseconds, the request updated meeting end time successfully.

API call will success with response 204 but does not update the end date as expected.

Hey @Wenbo,

None of our time formats in the API support sending milliseconds. Here is the correct template:
