Problems with conversion from milliseconds to date.

[rdvg...@gmail.com]

My app sends the date in milliseconds to a WS. Upon receiving it, I convert it to date format in the WS, but it appears to me with differences with respect to the initial value.

I decided to send the date in string format and as my logic in the app always uses the date in milliseconds, it seemed correct to create a method to return the date in string.

The problem I have is that he always returns me with a wrong month. I have tried to use DateUtil, but can't find a way to apply it.

My method is as follows and I appreciate the support.

    public static String cambiaNumeroFecha(Long fecha) {

        Calendar c = Calendar.getInstance();

        Date d = new Date(fecha);

         String r = Integer.toString(c.get(Calendar.YEAR)) + "-"

                + Integer.toString(c.get(Calendar.MONTH)) + "-"

                + Integer.toString(c.get(Calendar.DAY_OF_MONTH));

        return r;

    }

Sorry, correction:

   public static String cambiaNumeroFecha(Long fecha) {

        Calendar c = Calendar.getInstance();

        Date d = new Date(fecha);

        c.setTime(d);

Try this:

 public static String cambiaNumeroFecha(Long fecha) {

SimpleDateFormat dateFormat = new SimpleDateFormat();
dateFormat.applyPattern("yyyy-MM-dd");

        Date d = new Date(fecha);

         return dateFormat.format(d);

    }

Notice that date in milliseconds is in GMT/UTC so it should work well universally even if your server is in a different time zone (which is very likely). That's probably the source of the problem you're experiencing. This is why the response from Javier should work as it removes the time/location from the date and focuses on the calendar day.
