Sample timestamp on propel?

Question

Kohana

Good evening, the task is to implement a selection filter from the database.
There are:
1. input (date)/(datetime)
2. Cell in the database ('Mydate' int) containing unix timestamp, approx( 1460407052 ).
Propel is used to work with the database
An example of my use

$date = strtotime($filter['date']);
            $query->filterByMydate('%' . $date . '%', \Propel\Runtime\ActiveQuery\Criteria::LIKE);

Tell me how you need to register the filter, so that the selection by date would work?
