Question

I want to convert the time stamp (epoch time) to human readable string.

For that i am using calendar.setTimeInMillis(timeSinceEpoch) function to create the calender object and to get the date time string in human readable format.

I am confused on, How can I find out that the time stamp (epoch time) is of today or yesterday or it is in the same week as per the system’s current date and time?

Is there any API’s to achieve this in android?

Thanks.

Its really simple:

Calendar c=Calendar.getInstance();
c.getTimeInMillis();
String cur_day=String.format("%te %B %tY",c,c,c); // This will give date like 22 February 2012

c.setTimeInMillis(time);//set your saved timestamp
String that_day=String.format("%te %B %tY",c,c,c); //this will convert timestamp into format like 22 February 2012

//you can compare days,months,year,hours,minutes,seconds and milliseconds using above method.you can find various formats in below link
