在android中只获得毫秒的时间(Get only time in milliseconds in android)

 我想检查当前时间是否是00:01 AM然后做一个特定的工作我正在尝试将时间转换为毫秒，当我这样做时，我得到不同日期的不同毫秒值。 
 
 我试过这个： 
 
Calendar cal = Calendar.getInstance();

cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(getResources().getString(R.string.zerozero)));
cal.set(Calendar.MINUTE, Integer.parseInt(getResources().getString(R.string.one)));
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);


long alarmtime = cal.getTimeInMillis();
long currenttime = System.currentTimeMillis();

Log.e("Value", "= " + alarmtime + " " + currenttime);
 
 当我执行上述操作时：今天为毫秒：它显示为1458066660000 ，明天为： 1458153060000 
 
 那么如何检查当前时间是否为00:01 AM？ 
 
 如何比较当前时间与给定时间的简单方法..？ 
 
 谢谢！ 

I want to check if current time is 00:01AM then do a particular job for that I am trying convert only the time to milliseconds when I do that the I get different milliseconds value for different dates. 
 
I tried this:
 
Calendar cal = Calendar.getInstance();

cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(getResources().getString(R.string.zerozero)));
cal.set(Calendar.MINUTE, Integer.parseInt(getResources().getString(R.string.one)));
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);


long alarmtime = cal.getTimeInMillis();
long currenttime = System.currentTimeMillis();

Log.e("Value", "= " + alarmtime + " " + currenttime);
 
When I do the above: milliseconds for today: it shows 1458066660000 and for tomorrow it is :1458153060000
 
So how to check if current time is 00:01AM or not?
 
Easy way how to compare current Time with given time..?
 
Thanks!
