Convert from UNIX Timestamp to "Today at: currentTime" using Java

Question

I've tried to convert a UNIX Timestamp to todays date time.

Like I have a simple UNIX Timestamp and then I want to convert it like this:

Today at: theTimeFromMyTimestamp

Anyone that has a correct solution for this?

Thanks in advance!

Answer 1

Try this DateFormat.getDateFormat(mContext).format(new Date(myTimestamp * 1000))

As new Date() requires milliseconds instead of seconds, you have to multiple by 1000

Answer 2

You can also have a tighter control of the final format by making it explicit. It also avoids creating a Date object and needs no context:

DateFormat.format("dd/MM/yyyy hh:mm:ssaa", myTimeStamp * 1000L);

Answer 3

You need to convert the timestamp milisecond to long int by adding a L in the multiplication:

DateFormat.getDateFormat(mContext).format(new Date(myTimestamp * 1000L)) 

Answer 4

/**
 * Get the human readable String representation of time
 * @param unix_time
 * @return String format of time eg 13:20
 * @throws NullPointerException
 * @throws IllegalArgumentException
 */
public String convertFromUnix(String unix_time) throws NullPointerException, IllegalArgumentException{
    long time = Long.valueOf(unix_time);
    String result = "";
    Date date = new Date(time);
    SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
    format.setTimeZone(TimeZone.getTimeZone("GMT"));
    result = format.format(date);
    Log.d("date", format.format(date));

    return result;
}
