If you need to retrieve the timestamp with millisecond or microsecond resolution, then you can use the DateTimeInterface::format() function.

Example #2 Retrieving timestamp with milli and microsecond resolution

Stile orientato agli oggetti

<?php
$date
= new DateTimeImmutable();
$milli = (int) $date->format('Uv'); // Timestamp in milliseconds
$micro = (int) $date->format('Uu'); // Timestamp in microseconds

echo $milli, "\n", $micro, "\n";
?>

The above examples will output something similar to:
