As far as I understood, you need to calculate how many minutes are in the given hours and minutes. Well, I'd do it fast and simple:

String time = "725:00";
String[] parts = time.split(":",2);
int hours = Integer.valueOf(parts[0]);
int minutes = Integer.valueOf(parts[1]);
return hours*60+minutes;

With Groovy, you could do something like this:

def time = '720:00'
def minutes = time.split(':').with {
  (h,m) = it as int[]
  h * 60 + m
}

In Java use String.split(":") and take the second element of the array.

Assuming that the time is in "hour:minute" format.
