How can the microtime function be used to improve accuracy in timestamp calculations?

The microtime function can be used in combination with the time function to improve accuracy in timestamp calculations by providing a more precise measurement of time in microseconds. This can be particularly useful when measuring short intervals or when high precision is required in timestamp calculations. 

<?php
// Get current timestamp in microseconds
list($microseconds, $seconds) = explode(' ', microtime());
$timestamp = (float)$seconds + (float)$microseconds;

echo $timestamp; // Output the timestamp with microsecond accuracy
?>
