/**
 * Retrieve post published or modified time as a `DateTimeImmutable` object instance.

 * The object will be set to the timezone from WordPress settings.

 * For legacy reasons, this function allows to choose to instantiate from local or UTC time in database.
 * Normally this should make no difference to the result. However, the values might get out of sync in database,
 * typically because of timezone setting changes. The parameter ensures the ability to reproduce backwards
 * compatible behaviors in such cases.
