var time=date1.getTime()-date2.getTime();
var day=parseInt(time/(24*3600*1000));
var minutes=parseInt(parseInt(time%(24*3600*1000))/(60*1000));
var hour=parseInt(minutes/60);
var minute=parseInt(minutes%60);
day,hour,minute分别为天，小时，分钟的单位

要把时间转换为 java.util.Calender,要用到SimpleDateFormat
找一下Google

Java code:

public static String timeBetweens(Date from, Date to) {
final long ONEDAY = 86400000L; // 1天=86400000毫秒
final long ONEHOUR = 3600000L; // 1小时=3600000毫秒
final long ONEMIN = 60000L; // 1分钟=60000毫秒
long days = 0, hours = 0, mins = 0, secs = 0;
if (to.after(from)) {
secs = to.getTime() - from.getTime();
days = secs / ONEDAY;
secs = secs % ONEDAY;
hours = secs / ONEHOUR;
secs = secs % ONEHOUR;
mins = secs / ONEMIN;
