Comment:

 Encountered on a site, found that in some situations the `gmt_offset`
 option may get left empty -- seemingly due to plugin conflicts causing the
 save function to error out before `gmt_offset` gets stored.

 Here's an example set of reproduction instructions using WordPress 6.4.3
 and PHP 8.1.

 1. Install and activate aryo-activity-log
 2. Navigate to `/wp-admin/options-general.php` and change Timezone to UTC
 and Start of Week to Sunday
 3. Encounter the following fatal



 {{{

 4. Observe that the `gmt_offset` option is empty in the database.
 5.
 Revisit `/wp-admin/options-general.php`, observe critical error message
 under Date Format option, lack of Save button. Observe the following
 fatal.


 {{{

 int in /wordpress/core/6.4.3/wp-includes/functions.php:76

 j, Y')
 #2 {main}
   thrown in /wordpress/core/6.4.3/wp-includes/functions.php on line 76
 }}}

 #### Resolving

 To resolve, give the `gmt_offset` option a value.

 E.g., via WP-CLI:  `wp option update gmt_offset 0`
