Description

The following code:

<?php

$date = new DateTimeImmutable('2022-10-09 02:41:54.515330', new DateTimeZone('America/Los_Angeles'));
$now = new DateTimeImmutable('2022-10-10 08:41:54.534620', new DateTimeZone('UTC'));

var_dump($date->diff($now));

Resulted in this output:

object(DateInterval)#3 (16) {
  ["y"]=>
  int(-1)
  ["m"]=>
  int(11)
  ["d"]=>
  int(30)
  ["h"]=>
  int(0)
  ["i"]=>
  int(59)
  ["s"]=>
  int(59)
  ["f"]=>
  float(0.98071)
  ["weekday"]=>
  int(0)
  ["weekday_behavior"]=>
  int(0)
  ["first_last_day_of"]=>
  int(0)
  ["invert"]=>
  int(1)
  ["days"]=>
  int(0)
  ["special_type"]=>
  int(0)
  ["special_amount"]=>
  int(0)
  ["have_weekday_relative"]=>
  int(0)
  ["have_special_relative"]=>
  int(0)
}

But I expected this output instead:

object(DateInterval)#3 (16) {
  ["y"]=>
  int(0)
  ["m"]=>
  int(0)
  ["d"]=>
  int(0)
  ["h"]=>
  int(23)
  ["i"]=>
  int(0)
  ["s"]=>
  int(0)
  ["f"]=>
  float(0.01929)
  ["weekday"]=>
  int(0)
  ["weekday_behavior"]=>
  int(0)
  ["first_last_day_of"]=>
  int(0)
  ["invert"]=>
  int(0)
  ["days"]=>
  int(0)
  ["special_type"]=>
  int(0)
  ["special_amount"]=>
  int(0)
  ["have_weekday_relative"]=>
  int(0)
  ["have_special_relative"]=>
  int(0)
}
