Zoom invitation coming to client with wrong time zone

I'm sending a Zoom Invitation to a client.

- My computer is set up as Eastern Time Zone

- I'm setting the invitations up as the Eastern Time Zone

- My client is in the Eastern Time Zone

- My client's computer is set up as Eastern Time Zone

- When this client gets  the invitation (I'm using Outlook to send the invitation) he received is as Central (Chicago/America)

What's going on ?
