capture current date and time in a string

I would like to capture the date and time (at the moment of test execution), and post it in a message box in our tested web application.



I prefer to use Keyword mode testing. But I use code snippets whenever needed.



What would be the best and most clean approach, to capture the date (in format DD/MM/YY) and time (hh:mm:ss)  at the moment the test is run?



thanks!
