date_default_timezone_set
If you are studying date_format because you want to format a date, consider the power of date(..) !!!!
the mktime article has an example of adding days to a date of your choice and then formatting it:
echo date("M-d-Y", mktime(0, 0, 0, 12, 32, 1997))
where the 32 is like adding 1 day to the 31st .

The ISO8601 output format doesn't jive with (at least) what eBay expects in its SOAP transactions. eBay wants a UTC time with a 'Z' suffix. That is, eBay (and I'm guessing other web services) will accept "2007-05-04T17:01:17Z" but not "2007-05-04T17:01:17+0000". As it is, the built-in DateTime::ISO8601 format uses the +0000 timezone specifier even when in a UTC timezone.
As a workaround, I do this:
<?php
function get_ebay_UTC_8601(DateTime $time)
{ $t = clone $time;
$t->setTimezone(new DateTimeZone("UTC"));
return $t->format("Y-m-d\TH:i:s\Z");
}
?>
