Socket maximum timeout of 2147 seconds?

Description

The following code:

<?php
$url = 'https://example.com/';
$context = stream_context_create([
  'http' => [
    'timeout' => 60 * 60,
  ],
]);
file_get_contents($url, false, $context);

Resulted in this output:

file_get_contents(https://example.com/): Failed to open stream: timeout must be lower than 2147

But I expected this output instead:

No warning/error

Relavant code for the max value from the output ( floor((2^31 -1) / 1000000 ) = 2147 ):

Dividing by 100000.0 doesn't seem right.

The timeout struct accepts two long integers, one for seconds and one for micro seconds so the maximum value should be 2147483647.999999 seconds.
