What potential pitfalls should be considered when using strtotime() function in PHP to convert dates?

When using the strtotime() function in PHP to convert dates, potential pitfalls to consider include timezone discrepancies, ambiguous date formats, and limitations on the range of dates that can be converted. To address these issues, it's important to specify the timezone explicitly, use unambiguous date formats, and handle any errors that may occur during the conversion process. 

// Specify the timezone explicitly
date_default_timezone_set('America/New_York');

// Use unambiguous date formats
$date = '2022-01-15';

// Convert the date using strtotime() with error handling
$timestamp = strtotime($date);
if ($timestamp === false) {
    echo 'Invalid date format';
} else {
    echo date('Y-m-d', $timestamp);
}
