Data is not coming in laravel 5.4 after using timestamp in query

Data is not coming when comparing current time between 2 times to fetch data in Laravel. Both times are saved in the database as timestamp and in query also I am using timestamp. Below is the code i wrote:-

$current_date = strtotime(date('d-m-Y H:i:s'));
        
$bookings = MachineBooking::with('userDetail')->where('machine_id', $machine_id)->where('time_from', '>=', $current_date)->where('time_to', '<', $current_date)->get();

"time_from" and "time_to" both timestamps are saved in bigint format in database. I entered timestamp using search option in direct database also still data did not come. Can someone please tell me where i am making mistake.
