How can a developer correctly adjust the code to set a time duration of one minute?
To set a time duration of one minute in PHP, the developer can use the `strtotime` function to convert the time duration into seconds. They can then use this value in conjunction with the `time()` function to calculate the end time.
// Set time duration to 1 minute
$duration = 60; // 1 minute in seconds
// Calculate end time
$endTime = time() + $duration;
// Display end time
echo date('Y-m-d H:i:s', $endTime);
