java - 在黑莓中将日期转换为毫秒

Question

      DateTimePicker datePicker2 = DateTimePicker.createInstance();
      datePicker2.doModal();
      Calendar cal = datePicker2.getDateTime();
      Date date = cal.getTime();
      TimeZone _timeZone = TimeZone.getDefault();

      int month = cal.get(Calendar.MONTH);
      int year = cal.get(Calendar.YEAR);
      int date =cal.get(Calendar.DATE);
      int day = cal.get(Calendar.DAY_OF_WEEK);
      int hour = cal.get(Calendar.HOUR);
      int min = cal.get(Calendar.MINUTE);
      int sec = cal.get(Calendar.SECOND);

      int miliS33 = cal.get(Calendar.MILLISECOND);

我使用“datetimepicker”获取所选日期的所有字段，但我只想将此日期转换为毫秒，我该怎么做......我已经使用了

long gmtOffset = _timeZone.getOffset(1,year,month,date,day,miliS);但这对我不起作用。

请提供一些代码建议...!

Answer 1

只需这样做:

date.getTime();

记住这个方法

"Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT"
