There is a built in Rule that is used to create Popup Messages - the
Message Popup Rule.
You can use it in 3 different ways to create on screen messages using the Trainz Minibrowser in a Session.
- A simple text message with an optional graphic and sound
- A more complex web page with multiple graphics (and sound) - this requires you to create a separate HTML asset which is described at https://online.ts2009.com/mediaWiki/index.php/How_to_Create_a_HTML_Asset
- A string table built into a config.txt file
All are described on the Trainz Wiki page at
https://online.ts2009.com/mediaWiki/index.php/How_to_Use_Message_Popup_Rule
There is also a Wiki page showing sample applications at

Adding the Time of Day into a message could be more difficult. There is no Minibrowser function that I know of that would do that so it may require some scripting skills, an area outside my expertise.
