Dates and values are displayed in your time zone. Because the project could take place in a different time zone, the project schedule may appear incorrect message in the Project entity/table – Dynamics 365

We might get the below message/notification on opening the Project form –

Dates and values are displayed in your time zone. Because the project could take place in a different time zone, the project schedule may appear incorrect.

This message will appear if the Project’s timezone differs from the logged-in user’s timezone.

The project’s timezone is defined in the Calendar

For the user, it is defined in the user settings – Personalization Settings

Let us set it to be the same time zone as the project.

We will not get the notification now for that specific project.

If we check in detail, we can see below out-of-the-box method validateUserAndProjectTimezone getting fired on the onLoad of Project form, which fetches and compares the Timezone associated with the Project and Logged In User and shows the notification.
