Get timezone for a city?

[Robin S]

Does anyone know of a website/tool that will let me type in the name of a city, or maybe click on a map, and get the PHP-compatible timezone name for that location?

So for example if I typed or clicked on the location Christchurch, New Zealand I would get "Pacific/Auckland".

It doesn't need to be an API or anything - I just need some way to manually look up timezones for different locations.

I'm yet to find the perfect solution but so far I have found...

Search by location name (somewhat clunky and slow): https://www.geonames.org/

Click on map (can't search by name): https://askgeo.com/

Enter latitude and longitude (can't search by name): https://timezonedb.com/

For my needs I prefer a web interface but if I wanted or could be bothered with an API I found several listed in this StackOverflow answer.

To me it looks like https://www.timeanddate.com/time/map/ is doing what you're after.
You can search by name and then you have the timezone of the city you've entered inside the "Timezone" tab.

Thanks, but I already looked at this one and it doesn't give the timezone in the PHP name format I linked to in my post. It gives a timezone like "PST" when I need "America/Los_Angeles".

Maybe this would do it:

There's a really useful page https://stackoverflow.com/tags/timezone/info - though it'll make you realise you're opening something of a can of worms! 

I think, but I'm definitely not sure, that PHP uses the IANA/Olson Time Zone Database (linked on the above page). However, even if it does, I don't know how up to date PHPs list of time zones is.

The Geolite2 database from MaxMind, at https://dev.maxmind.com/geoip/geoip2/geolite2/, is free and gives IANA time zone codes. This is another option: https://www.ip2location.com/free/olson-timezone. And there may well be quite a few other such sources out there.

I don't know of any ready-made tool, but that doesn't mean there isn't one!

Nice, that's the quickest and easiest I've seen so far. Thanks!

The PHP timezones are stored in timezonedb, which is updated regularly: https://pecl.php.net/package/timezonedb

You can check which version is used in your environment via timezone_version_get().

Thanks @Robin S, useful to know.
