以毫秒转换为年，月，天数的最佳方法 [英] Best way to convert Milliseconds to number of years, months and days

问题描述

我试图毫秒日期转换的年 月 周数和天。

例如：5个月，2周和3天或 1年零1天

我不希望： 7天或4周>这应该是 1周和1个月。

我试过一些方法，但它始终成为像 7天，0周。

我的code：

  INT周=（INT）Math.abs（timeInMillis /（24 * 60 * 60 * 1000 * 7））;
INT天数=（INT）timeInMillis /（24 * 60 * 60 * 1000）+1）;
 

我要加1天数，因为如果我有23个分，这应该是1天。

请解释一下如何将它正确地转换，我认为有更有效的方式来做到这一点。

解决方案

我总是用这从毫秒获得年等，反之亦然。到现在我已经与它没有任何问题。希望它帮助。

 进口java.util.Calendar中;日历C = Calendar.getInstance（）;
//以毫秒为单位设置时间
c.setTimeInMillis（毫秒）;
INT mYear = c.get（Calendar.YEAR）;
INT mMonth = c.get（的Calendar.MONTH）;
INT MDAY = c.get（Calendar.DAY_OF_MONTH）;
INT HR = c.get（Calendar.HOUR）;
INT分钟= c.get（Calendar.MINUTE）;
INT秒= c.get（Calendar.SECOND）;
 

I'm trying to convert a Milliseconds date to number of years months weeks and days.

For example: 5 months, 2 weeks and 3 days or 1 year and 1 day.

I don't want: 7 days or 4 weeks > this should be 1 week and 1 month.

I tried few ways but it always became something like 7 days and 0 weeks.

My code:

int weeks = (int) Math.abs(timeInMillis / (24 * 60 * 60 * 1000 * 7));
int days = (int) timeInMillis / (24 * 60 * 60 * 1000)+1);

I have to add 1 to number of days because if I have 23 hours it should be 1 day.

Please explain how to convert it correctly, I think that there is more efficient ways to do it.

解决方案

I always use this for getting years etc from milliseconds and vice versa. Till now I've had no problems with it. Hope it helps.

import java.util.Calendar;

Calendar c = Calendar.getInstance(); 
//Set time in milliseconds
c.setTimeInMillis(milliseconds);
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH); 
int mDay = c.get(Calendar.DAY_OF_MONTH);
int hr = c.get(Calendar.HOUR);
int min = c.get(Calendar.MINUTE);
int sec = c.get(Calendar.SECOND);
