Comment (by SergeyBiryukov):

 In [changeset:"59465" 59465]:
 {{{
 #!CommitTicketReference repository="" revision="59465"
 Coding Standards: Cast `gmdate( 'Z' )` to an integer before addition.

 This addresses two instances of the (numeric string) `gmdate( 'Z' )` being
 added to an `int` value.

 Affected functions:
 * `upgrade_110()`
 * `WP_Date_Query::validate_date_values()`

 Follow-up to [942], [29925], [45424].

 Props justlevine.
 See #52217.
