What potential issues or pitfalls should be considered when converting time values in PHP?
One potential issue when converting time values in PHP is handling different time zones. To ensure accurate conversions, it's important to set the appropriate time zone before performing any time-related operations. This can be done using the `date_default_timezone_set()` function with the desired time zone as a parameter.
// Set the desired time zone
date_default_timezone_set('America/New_York');
// Perform time conversion operations here
