Future time in gmail from yahoo.com ?

So I have strange problem, got an email from a yahoo.com (got many emails before) and it shows a future date for some reason, as you can see the current time (I checked other times) are correct. Not sure what the problem is or if it showed up for anyone else. Where to report this? please advise. 

PHP Month Number to Month Name the Easy Way

Very simple solution from here (posted for archive purposes):

<?php
$monthNum = 5;
$monthName = date("F", mktime(0, 0, 0, $monthNum, 10));
echo $monthName; //output: May
?>
