 I have openSuSE 15.1, nginx 1.14.2, hhvm 3.30.5 and MariaDB. I install
 WordPress 5.3+ and a faced with a problem. Site and CP not working and get
 500 error.
 There's error from hhvm:
 {{{

 After some examination I found out what the problem is. It's new function
 get_post_datetime. I don't why but date_create_immutable_from_format
 method don't work. I try to use date_create_from_format or
 DateTimeImmutable::createFromFormat() and it worked.
