Converting time stamp in SECONDS to a calendar date format.. problems

Question

Hello. I'm trying to convert a long interger that represents the number of SECONDS passed since the 1970 date
the number was originally generated by php's mktime() function
one of the numbers I have for example is this : 1126933200
I haven't done the math but this is a date probably around september of 2005.. it's irrelevant anyhow.
I want to convert this to a date format I can use in java. I've tried to create a new date like so :
Date date = new Date(1126933200);
I've also tried it with the calendar method like so :
Calendar calendar = new GregorianCalendar();
calendar.setTimeInMillis(1126933200);
it was only then that I realized that both these methods require the number of MILLI seconds. So I tried doing a simple multiplication by 1000 on my original number and then I started getting a "integer number too large" error when trying to compile.
so i'm kind of at a loss here.. i figure I could make a function myself that would divide my number in days of 86400 seconds.. and then i'd have to keep in mind the bisectal (sp) and the months with more and less days etc.. but i'm sure there must be an easier way.
and i don't get why a method who's meant to receive a very long number is giving me an error when i try to give one to it.
your help is appreciated as always. thanks

Note you also need to define what timezone that seconds number represents.
With Gregorian it is going to use the local timezone (the code here will anyways). The code using Date is using the UTC timezone.
