Timezone string doesn't return in REST API /wp-json/wp/v2/settings

[phakphumvis]

Timezone string in REST API /wp-json/wp/v2/settings always return as an empty string even set any timezone from Admin panel -> Settings.

timezone string return empty value if you set manual offsets value ( e.g.: UTC -12 ) from Settings->General->Timezone. Better use wp_timezone_string() if timezone value is found empty when using the /wp-json/wp/v2/settings endpoint.

@opurockey Thanks for the feedback! I’ve revised the code based on your suggestion.

This behaviour is intentional; if the timezone is set via gmt_offset, we want to clearly convey this to clients, rather than a potentially inaccurate timezone.

For example, if the site is set to UTC+1, that would currently (with DST) map to Europe/London, but during winter would map to Europe/Paris. We cannot disambiguate between these, so providing that information clearly to clients is intentional.

Agreed with the above. That's why clients like Gutenberg check for both settings. i.e. if there's no timezone string, one should fall back to the offset.
