或者使用Java8和Groovy2.3RC（如果你想站在最前沿）;- ）

import java.time.*

LocalDate today    = LocalDate.now()
LocalDate birthday = LocalDate.of( 1982, Month.AUGUST, 8 )

Period period = Period.between( birthday, today )

println """$period.years years, 
          |$period.months months, 
          |$period.days days""".stripMargin()

下面是一个使用joda time的圆滑替代方案：）

@Grab('joda-time:joda-time:2.3')
import org.joda.time.Period
import org.joda.time.DateTime

def now = new DateTime()
def dob = new DateTime(1982, 8, 21, 0, 0)

def period = new Period(dob, now)

println """$period.years years, 
         |$period.months months, 
         |$period.days days, 
         |$period.hours hours, 
         |$period.minutes minutes
        """.stripMargin()

对我来说，joda不可用，所以我搜索了另一个更groovy的解决方案，发现：

def duration = groovy.time.TimeCategory.minus(
  new Date(),//date1
  new Date(session.creationTime)//date2
);
println "seconds: " + dur2.seconds;
println "min: " + dur2.minutes;
println "hours: " + dur2.hours;

def current = new Date（）println current def dob = new Date（'06/27/2000'）println dob def res = current - dob def age = res/365 println age

import com.sap.it.api.mapping.*;

def String customFunc(String DOB){
if(DOB == '')    
{
DOB = '';
return DOB;
}
else
{
Date birth_yr=new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS").parse(DOB);
Date date = new Date();
def duration = groovy.time.TimeCategory.minus(date,birth_yr);
def age = (duration.days).intdiv(365)
return age
} 
}
