What potential pitfalls should be considered when converting dates into timestamps in PHP?

When converting dates into timestamps in PHP, it is important to consider time zones. If the time zone is not specified, the default time zone of the server will be used, which may lead to incorrect timestamp conversions. To ensure accurate conversions, always set the appropriate time zone before converting dates into timestamps using the `date_default_timezone_set()` function. 

// Set the appropriate time zone
date_default_timezone_set('America/New_York');

// Convert date into timestamp
$date = '2022-01-01';
$timestamp = strtotime($date);

echo $timestamp;
