Adding non-related widgets to dashboards

Im currently designing an internal application which will get used by a large amount of employees in our company. The application will be used for stuff like managing customer data, changing contracts, uploading documents etc.

One part of the application will be the dashboard, which will be the only area that displays kind of "personal" or user-related data.

Of course there will be graphs and diagrams that display performance and stuff like this but now im wondering if it is recommended to display data that is not application related just as a little "extra" and to make the user feel a bit better.

Example:

Hello Thomas, its Friday the 21th and the current temperature is 20°.

The part of the date could be useful since the users often communicate with customers via phone and exchange data, so i could avoid making them leave the application and checking the date on their operating system but stuff like the weather information would not be application related at all.

Or maybe add a widget that shows some quotes or facts once a day so users actually get excited to open the application for the first time each day (since they will open it every day).

Would you say stuff like this adds unnecessary weight or can add a nice little touch to the UX?
