DateTime not working with1.3.6?

[GeneticAlpha]

So I have this seasons code:

$today = new DateTime();
if(new DateTime() < new DateTime($today->format('Y').'-3-20 00:00:00')) $season = "Winter <img src=''>";
else if (new DateTime() < new DateTime($today->format('Y').'-6-21 00:00:00')) $season = "Spring ";
else if (new DateTime() < new DateTime($today->format('Y').'-9-22 00:00:00')) $season = "Summer <img src=''>";
else if (new DateTime() < new DateTime($today->format('Y').'-12-20 00:00:00')) $season = "Fall <img src=''>";
else $season = "Winter <img src=''>";
$this->moneyBar->add(new Comment("<b id='season'>{$season}</b><br>"));

That works for both my sites, and for some reason my friend's 1.3.6 site isn't allowing the code and makes an error across the page. Any idea how I can fix this? It's not accepting the new DateTime() function.

For Mys v1.3.6, you need to add this line to the top of the file following the <?php tag:

use DateTime;

This is because every file/class in Mys v1.3.6 is namespaced, unlike Mys v1.3.5 and earlier in which only files/classes in the /classes folder have namespace. PHP will not import built-in classes unless you write a use statement, its annoying(most programming languages dont work like this) but we have to deal with it.

Thank you so much! This worked I only know basic code so I had no idea how to fix that XD
