Java: epoch date to MM/DD/YYYY

问题

My time: 1386696238

My code:

Date date = new Date(Long.parseLong(currentNotification.getDate_created()));
        SimpleDateFormat formatter = new SimpleDateFormat("MM/DD/yyyy", Locale.getDefault());
        String dateString = formatter.format(date);

My result: 1/16/1970

Desired result: 12/10/2013

What am I doing wrong?

回答1:

Your value is in seconds, so you need to multiply it by 1000.

Also, DD is day of year, you want dd:

SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy", Locale.getDefault());

回答2:

I suppose you should multiply your input with 1000 (UNIX timestamp in seconds, but Java j.u.Date in milliseconds).

Edit:

Oh another mistake in your code: The pattern symbol should be d, not D (day-of-year).
