Magento 2 Collection Date Filter out by one hour

I have an issue where I filter a collection by date and the item I expect to get is not being returned in the collection, however if I print out the SQL that the collection uses and run that against my database the item is returned.

$from = new \DateTime($lsDate);
$orders = $this->_orderCollectionFactory->create()
        ->addFieldToSelect(['grand_total', 'created_at'])
        ->addAttributeToFilter('created_at', array('gteq' => $from->format('Y-m-d H:i:s')))
        ->addAttributeToFilter('customer_id',$customer->getId())
        ->setPageSize(10)
        ->setOrder('created_at', 'desc');

$from->format('Y-m-d H:i:s') // Lets say this is 2019-08-06 15:33:00
$this->logger->info(count($orders)); // This is 0

If I print out the SQL that this generates it looks something like this:

SELECT `main_table`.`entity_id`, `main_table`.`grand_total`, `main_table`.`created_at` FROM `sales_order` AS `main_table` WHERE (`created_at` >= '2019-08-06 15:33:21')

The orders created_at date that should be returned is 2019-08-06 15:34:00.

If i run the above query on my database it returns the one order above however as you can see in my code above the collection is empty.

If i change the date of the order to be 2019-08-06 16:34:21 (one hour in the future) the code then returns a collection with one item. It looks like it has something to do with the timezone somwehere? Maybe DST (Daylight Saving Time)?
