Finding time stamp in java

Question

Dear friends,
I am new in java. I would like to convert epoch second to actual date .
I have used this below line in my application it has given worng date.
Date now=new Date(Integer.parseInt(callid[1])*1000);
String date = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(now);
System.out.println(date);
Note:  callid[1] is having epoch second in string manner. That epoch second is *"1279538252"*
Output of this above code is,
* 28/12/1969 00:56:37*
But actual date of the epoch is,
* Monday 19 July 2010 04:47:32 PM IST*
What I have done wrong here ?
Please help me..

Well, you are right - but speed is I guess the least of all concerns here.I'm talking about the fact that I responded after you - not the speed of your code.
I only wanted to outline that he started out with Integer instead of Long.My solution was to use 1000L rather than just 1000 but it leads to the same result. Your solution allows a bigger range of seconds than mine but ...
However, parsing some internal representation and calculating with it is for sure not the way he should go with.Unlike you, I don't disagree with the OP's basic approach but I do question his diagnostic abilities. All the OP had to do was print out the value of the product
Integer.parseInt(callid[1])*1000 and he would have seen exactly what was wrong! There would then have been no need to post this as a problem!
