Are there any potential pitfalls to be aware of when using strtotime() and date() functions for date manipulations in PHP?

When using strtotime() and date() functions for date manipulations in PHP, one potential pitfall to be aware of is the reliance on the server's timezone settings. If the server's timezone is not set correctly, it can lead to unexpected results when converting and formatting dates. To avoid this issue, it's recommended to explicitly set the timezone using date_default_timezone_set() before using strtotime() and date() functions. 

// Set the timezone to the desired value
date_default_timezone_set('America/New_York');

// Example usage of strtotime() and date() functions with explicit timezone setting
$timestamp = strtotime('2022-01-01');
$formatted_date = date('Y-m-d', $timestamp);

echo $formatted_date; // Output: 2022-01-01
