 In https://github.com/WordPress/gutenberg/pull/56682 I'm proposing to add
 a timezone offset value for displaying purposes, to be used in the
 Gutenberg editor.

 Right now, the editor is displaying the stored value which is a float
 number with decimals. For some timezone offsets, that displays incorrect
 values in the UI like `5:75` instead of `5:45`.

 There's already a couple places in Core where such a conversion is in
 place for displaying purposes:
 - In [https://github.com/WordPress/wordpress-
 develop/blob/7c492d36e0c6e219e54ce22eb6d1f5ae4610092b/src/wp-
 includes/functions.php#L6701 the select element] for the Timezone setting.
 - In the customizer [https://github.com/WordPress/wordpress-
 develop/blob/7c492d36e0c6e219e54ce22eb6d1f5ae4610092b/src/wp-
 includes/customize/class-wp-customize-date-time-control.php#L306-L318
 WP_Customize_Date_Time_Control class].


 It would be a one line addition:

 {{{
 'offsetFormatted' => str_replace( array( '.25', '.5', '.75' ), array(
 ':15', ':30', ':45' ), (string) get_option( 'gmt_offset', 0 ),
 }}}
