General Support: fixing date_default_timezone_set() error

if anyone else was getting
<blockquote>Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for 'UTC/0.0/no DST' instead in /scioly/mentorhigh.com/gallery/plog-includes/plog-functions.php on line 2666</blockquote>
or the like above all of their images after the recent php upgrade, adding

<code>date_default_timezone_set('UTC');</code>

at the beginning of plog-includes/plog-functions.php on the first line after the <?php start tag fixed the issue for me.

<code>
<?php

date_default_timezone_set('EST');
</code>
