Appointment created by ews-javascript-api are shown in Monrovia timezone

can you check this in outlook web instead of outlook client?
also check what is the value you get for ews.TimeZoneInfo.Local on your server, this auto timezone detection is not very perfect

@gautamsi thanks for the quick reply
Unfortunately, the issue is on a production server of a client where they have on-premise exchange server. I don't have access to outlook web there.

our nodejs app is on aws , I will add some logs on production and see what value for ews.TimeZoneInfo.Local and re-send it here .
just to make sure that I understand , setting event.StartTimeZone = ews.TimeZoneInfo.Local will get the timezone of nodejs server (aws in our case ) and set it to be the timezone of the appointment ? if yes , then its not what I am looking for .

my goal to show the appointment on the same timezone as the user's timezone
for example if I am sending "2024-06-04T10:30:00.000Z" as start date , it should appear for a user in Berlin as 11:30 (UTC+1)

On the testing environment, we are only provided with outlook web that is also hosted by the client and I don't see this issue on outlook web

you would want to find user timezone and use that timezone instead. if you use ews.TimeZoneInfo.Local it uses moment.tz.guess() which is not something in my control. You have to either set the timezone in code or get it for each user and construct the timezone based on that.
