strtotime返回错误的一天

Question

When using the following

echo date('D',strtotime("2013-06-16T06:00:00-07:00"));
echo date('D',strtotime("2013-06-16T18:00:00-07:00"));

First it returns Sun and the Second returns Mon. I'm not really sure why or how to correct! The Date:"2013-06-16T06:00:00-07:00" is data I'm retrieving from a XML file. The timestamp has the correction for UTC at the end not sure if this is generating the error.

Thanks for any help.

To get expected results you should consider using DateTime():

<?php
echo date('D',strtotime("2013-06-16T06:00:00-07:00")) . "
";
echo date('D',strtotime("2013-06-16T18:00:00-07:00")) . "
";;

$dt1 = new DateTime("2013-06-16T06:00:00-07:00");
$dt2 = new DateTime("2013-06-16T18:00:00-07:00");
echo $dt1->format('D') . "
";
echo $dt2->format('D') . "
";

Output

Sun
Mon
Sun
Sun
