convert timestamp to date time in new york

I'd love to help, but can you put a bit more detail in it.  Like where are we getting the date stamp from, what format.  What time zone is the server in. Something, anything.

A lot of information about the PHP Date function is available here:
http://php.net/manual/en/function.date.php

Additioinally the newer versions of PHP allow you to specify time zone.

Unix timestamp 432403200

Found this interesting page on converting epoch time:
http://www.epochconverter.com/

date(output format, epoch); Output format example: 'r' = RFC 2822 date

Knowing the original time zone would help but the following code:

<?php
$test = date("l, F j, Y, g:i a",432403200 ); 
print $test;
?>

yields: Wednesday, September 14, 1983, 12:00 pm

Ray, wouldn't that depend on what his problem actually is?

I read it as converting an already existing date/time stamp to new york time, not the current date time.

A datetime value is a string of data, and it is always localized, whether or not localization is shown in the string.  A timestamp is an integer.

In the date() function the second argument, if omitted, is the integer value of time(), which is the same everywhere in the world, even though there are different timezones and there is that International Date Line.  It screws up your medications when you cross it ;-)
http://php.net/manual/en/function.date.php

The date_default_timezone_set() function tells PHP what the localization is for the date() function and some other things, like the strtotime() function.

combine these two answers.
