Neat site. How does it know my local time?

  Getting of your browser?

    Yes - but how? I looked at the HTTP headers I was sending and none of them contained the time zone.

      Open your console and type `new Date()`. In JS every date is local time by default
      • avg_dev 9y ago
        Sure, but there is no JS on the page, and curling https://api.epoch.sh https://api.epoch.sh gives the same result.

  IP sniffing?

  Looking at the response headers, could they be inferring the timezone based on what cloud front server the user hits? Edit: This is probably way over thinking it, but here are the Amazon data center IP's. Search "CLOUDFRONT" https://ip-ranges.amazonaws.com/ip-ranges.json https://ip-ranges.amazonaws.com/ip-ranges.json to see the list of regions.

  IP geolocation - try it from a proxy.

  Geo lookup on your IP to get a time zone. Easy to spoof with a proxy / vpn.
