How do I make text that displays the current date and time in realtime?

The community member is experiencing an issue where the "dataTime attritube is not set". The comments suggest that this issue can be addressed with JavaScript, and a specific GitHub issue (https://github.com/webstudio-is/webstudio/issues/3510) will address it. However, the solution will only work on page load and will not provide a clock-like update while the user is on the page.
