    Time Keep – Location timezones, timers, alarms, countdowns in one place▲26

    I kept running into this: timer on my laptop, alarm on my phone, timezone / discord timestamp conversion app in a separate tab. Switching between them was a hassle and I wanted to be able to set them up and manage really fast anywhere I was. So I built Time Keep, it puts world clocks, timers, alarms, countdowns, a stopwatch, breaks, a sleep planner, Discord timestamps, and more into one always open place. Works without an account or signup. All tools are fully functional immediately. Sign in to save your data across sessions. Pro adds live cross-device sync. Shared countdown links show…

    A Unix timestamp converter that includes the micro and nanoseconds▲27

    I find myself having to convert a lot of unix timestamps to a human readable format, but most of the online calculators I found don't include the micro or nanoseconds in the human readable output. It's a small detail, but I find myself having to manually space out the timestamp frequently. I'm learning frontend development, so I made this converter to hopefully make it easier to convert timestamps. Welcome to any feedback :)

    httpclock. A useless way to tell the time with HTTP status codes…▲5

    I made this a few months back as a fun little project and it has absolutely no utility whatsoever. The server returns the current time in the request's status code — i.e., as long as the time can be mapped to a valid HTTP status code (e.g., 4:04pm -> 404 Not found) the server returns that status code for the request. Example: https://x.com/scottinallcaps/status/1827211120194486597 The httpclock.com domain detects timezone by IP and redirects to the respective subdomain such as pt.httpclock.com (but will fall back to UTC) A browser will show a blank page for most of…
