Is there anywhere that shows the screen time of characters in movies?

I'm specifically looking for the screen time of the characters Rose DewItt Bukater (Kate Winslet) and Jack Dawson (Leonardo Dicaprio) in Titanic (1997). Is there a website available for viewing this sort of information or is there another means I can get this from? Tried Googling it but didn't find any answers.
