Issues with default timezone | WordPress.org

Hello,

Trying to install at a new site but getting months listed with December on top of the list and weekends marked for Fridays and Saturdays…

Checked site’s Health Check and getting this:

PHP default timezone is invalid
PHP default timezone was changed after WordPress loading by a date_default_timezone_set() function call. This interferes with correct calculations of dates and times.

Any clues?

Thanks.
