Adding run times in Goovy using java.sql.Time class

I'm trying to figure out a way add run times of interviews in the s开发者_如何学Goystem I'm working on in Groovy.

In my code I have an ArrayList of java.sql.Time objects ("times" in the below code) I would like to sum the total time of the interviews in the ArrayList with a closure. But I cannot find a valid way to add together to java.sql.Times. So, if my ArrayList contains the sql times "00:01:30" and "00:02:30" the method would return "00:04:00".

def sumTime(java.util.ArrayList times) {    
  def sum = java.sql.Time.valueOf("00:00:00")        
  times.each() { x ->
    //add current list member to sum              
  }
  return sum
}

Thanks,

Don

You can do this (edit this works in both the webconsole and the desktop console):

import java.sql.Time

def timeList = [
  Time.valueOf( '00:01:30' ),
  Time.valueOf( '00:02:30' ),
]

def sumTime( times ) {
  long zero = Time.valueOf( '00:00:00' ).time
  new Time( zero + times.sum { it.time - zero } )
}

println sumTime( timeList )

which prints

00:04:00

as required

The original issue with this code is that on the Google App Engine JDK, new Time( '00:00:00' ).time returns 0, wheras on the ex-Sun 1.6 JVM, the same code returns -3600000
