Google App Engine had this quite a while ago (almost a decade, I think)and a very generous free tier. Also has approx lat-long, city, state and country.

I lost track of the consumer apps I've used this on and still haven't received a $1+ bill.

Is there a good lat/lon to timezone database that lets you leverage this into a presumptive timezone offset from UTC and thus local time?

[jonathan-kosgei]

I built something similar for https://ipdata.co. The API will return a time object like this for any IP:

    "time_zone": {
        "name": "America/Chicago",
        "abbr": "CDT",
        "offset": "-0500",
        "is_dst": true,
        "current_time": "2020-07-25T06:10:16.945136-05:00"
    }

Do you need the lat/lon for this? Usually you'd just put in the nearest city.

Moment.js is probably the most prevalent time and date library.

Try https://blip.runway7.net/v2.beta – I've added unix timezone based on the country and state code. The ISO databases have timezones associated with the level 2 code, which roughly corresponds to a state inside a country.

Can’t you just ask the client which timezone it’s in? Every browser knows, and it will be a more accurate answer: the user might be on a foreign VPN or temporarily in another TZ, but not working on that timezone.

My application is not browser-based.

I’d like to set a system clock timezone via geoip only, without location lookup via wifi. On my more secure systems I have location services disabled and it’d be nice to have an accurate local time automatically.

I have a need for this too, and considering making a basic service for it.

[sudhirj]

https://blip.runway7.net/v2.beta should work for you, let me know if it doesn't?

[sudhirj]

I actually can’t remember :-/ will fish it out and set up a proper service, maybe paid.

Where is the source code for v2.beta? It’s not on your GitHub.

Hi!

I need to be able to send a lat/long/timestamp to get tinezone.
