在Blackberry应用程序中获得两个不同时间戳的差异

Question

我想知道如何计算Blackberry应用程序中两个不同时区/时间戳之间的差异。

例如计算服务器时间戳和客户端时间戳的差异

请帮忙。 感谢。

试试这段代码：

class Scr extends MainScreen {
 public Scr() {
  String time1 = "2009-11-27 01:38:05";
  String zone1 = "Pacific/Midway";
  String time2 = "2008-05-01 12:38:05";
  String zone2 = "MST";

  long timeDiff = getTimeDifference(time1, zone1, time2, zone2);
  Date date = new Date(timeDiff);
  add(new LabelField(String.valueOf(date)));
 }

 public long getTimeDifference(String timestamp1, String timezone1,
   String timestamp2, String timezone2) {
  long time1 = getTime(timestamp1, TimeZone.getTimeZone(timezone1));
  long time2 = getTime(timestamp2, TimeZone.getTimeZone(timezone2));
  return time2 - time1;
 }

 public long getTime(String time, TimeZone timeZone) {
  Date formatter = new Date(HttpDateParser.parse(time));
  int offset = timeZone.getRawOffset();
  return formatter.getTime() + offset;
 }
}
