$datetime = date("Y-m-d H:i:s", $time); // Date and time after subtraction
Subtract Minutes from currenttime:
$date = date("Y-m-d H:i:s"); // Current date and time
$currentDate = strtotime($date); // Convert into Unix timestamp
$time = $currentDate - (5 * 60); // Subtract Minutes from currentdate
$datetime = date("Y-m-d H:i:s", $time); // Date and time after subtraction
Subtract Seconds from Datetime
$date = date("Y-m-d H:i:s"); // Current date and time
$currentDate = strtotime($date); // Convert into Unix timestamp
$time = $currentDate - 50; // Subtract Seconds from currentdate
$datetime = date("Y-m-d H:i:s", $time); // Date and time after subtraction
