android - Converting seconds to date time String

Question

I have seconds from epoch time and want to convert it to Day-Month-Year HH:MM
I have tried following but it gives me wrong value.

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(seconds*1000);
String dateString = calendar.get(Calendar.DAY_OF_WEEK) + ", "+.......

Above code is not working properly am i doing anything wrong here.

For example if seconds = 1299671538 then it generates time string as Friday, December 12, 1969 which is wrong it should display Wednesday, March 09, 2011

Answer 1

For example if seconds = 1299671538 then it generates time string as Friday, December 12, 1969 which is wrong it should display Wednesday, March 09, 2011

You have integer overflow. Just use the following (notice "L" after 1000 constant):

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(seconds*1000L);
String dateString = calendar.get(Calendar.DAY_OF_WEEK) + ", "+.......

or better use SimpleDateFormat class:

SimpleDateFormat formatter = new SimpleDateFormat("EEEE, MMMM d, yyyy HH:mm");
String dateString = formatter.format(new Date(seconds * 1000L));

this will give you the following date string for your original seconds input: Wednesday, March 9, 2011 13:52
