convert timestamp to date
提问by TechnocraT
I'm getting the date from an sms message in android as a time stamp in seconds or milliseconds from epoch.I need to display it as standard date and time using java.
我从 android 中的 sms 消息中获取日期作为时间戳（以秒或毫秒为单位）。我需要使用 java 将其显示为标准日期和时间。
int date = (cursor.getColumnIndex(SmsReceiver.DATE));
this returns some number like 1308114404722.
这将返回一些数字，如 1308114404722。
what is the process to use this number and display as current date
使用此数字并显示为当前日期的过程是什么

int date = ...
Date dateObj = new Date(date);
To format a Dateobject, use for example SimpleDateFormat:
要格式化Date对象，请使用例如SimpleDateFormat：
DateFormat df = new SimpleDateFormat("dd-MM-yyyy");
String text = df.format(dateObj);
Also, you should store number-of-milliseconds-since-epoch values in a long, not in an int, because an intis not large enough. (In fact, the number 1308114404722 doesn't even fit in a 32-bit int).
此外，您应该将 number-of-milliseconds-since-epoch 值存储在 a 中long，而不是 an 中int，因为 anint不够大。（实际上，数字 1308114404722 甚至不适合 32 位int）。

SimpleDateFormat formatter = new SimpleDateFormat("HH:mm dd.MM.yyyy");
Date date = new Date(1308114404722);
Calendar cal = Calendar.getInstance();
cal.setTime(date);

Try:
尝试：
DateFormat df = DateFormat.getInstance();
String dateStr = df.format( new Date( date ) );

I suppose that this is Epoch Timestamp to convert it to human readable form use
我想这是 Epoch Timestamp 将其转换为人类可读的形式使用
int date = (cursor.getColumnIndex(SmsReceiver.DATE));
String date = new java.text.SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(new java.util.Date (date*1000));
hopefully this will work as on converting this value: 1308114404722
希望这将在转换此值时起作用：1308114404722

To convert the unix time stamp that you are getting to a normal date use this snippet of code:
要将您获得的 unix 时间戳转换为正常日期，请使用以下代码片段：
//date here should be a long
//这里的日期应该很长
long date = (cursor.getColumnIndex(SmsReceiver.DATE));
长日期 = (cursor.getColumnIndex(SmsReceiver.DATE));
String standardDate=DateFormat.getDateInstance().format(new Date(date);
String standardDate=DateFormat.getDateInstance().format(new Date(date);

You can use like that
你可以这样使用
public static java.util.Date toDate(java.sql.Timestamp timestamp) {
long millisec = timestamp.getTime() + (timestamp.getNanos() / 1000000);
return new Date(millisec);
}
