long millisecond = beginupd.getTime();
Date.getTime() JavaDoc states:
Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

long milli = date.getTime();
This is for get time in milliseconds.

You could use
Calendar cal = Calendar.getInstance();
cal.setTime(beginupd);
long millis = cal.getTimeInMillis();

beginupd.getTime()将给你自1970年1月1日00:00:00 GMT到你在Date对象中指定的时间以毫秒为单位的时间
