DateTimeImmutable::diff differences in 8.1.10 onwards - timezone related. #9699
Description
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)
}

America/Los_angeles: 2022 dom 13 mar, 2.00 PST → PDT +1 hour (DST start) UTC-7
Problem of documentation: change From 8.1.0 diff convert from local "America/Los_angeles" 2022-10-09 02:41:54.515330 to "UTC local from America/Los_angeles" 2022-10-09 02:41:54.515330. Previous or PHP >= 8.1.10
"UTC" 2022-10-09 09:41:54.515330
@derickr The change creates more breaks than advantages. Please restore 23 hours if timezone != same type. (Never 23 hours is one day for != timezone convert with timezone $originObject and $targetObject UTC).
PHP >= 8.1.10 Timezone same type https://bugs.php.net/bug.php?id=81458
Fixed phpGH-9699, phpGH-9866, and phpGH-9880 (problems with diff); and …
