How can PHP developers ensure accurate time calculations when using timestamps in their code?

To ensure accurate time calculations when using timestamps in PHP, developers should always set the timezone explicitly before performing any time-related operations. This ensures that the timestamps are interpreted correctly based on the specified timezone. 

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

// Perform time calculations using timestamps
$timestamp = time();
echo date('Y-m-d H:i:s', $timestamp);
