As an enhancement let me suggest that the current way to print the Execution Info could be more readable.

As per my screenshot, you can see the time has three zeros at the end and most of the time these could be removed, infact the report.html from robot doesn't print those three zeros

This suggestion applies to Start Time, End Time and Duration fields.

robotframework 7.1rc2
robotframework-metrics 3.7.0
Python 3.11.4

Best regards
