UTC Time - live clock, ISO 8601, Unix timestamp

In plain words

UTC Time is a live clock displaying the current time in UTC with one-click copying of ISO 8601, RFC 3339, RFC 2822, and Unix timestamp formats. It's built for developers who need quick access to standardized time formats and includes a device clock-skew checker, code snippets for 14 programming languages, and a free JSON API. The tool features timezone lookups by city, airport code, and IATA abbreviations, runs fast with a dark interface, requires no signup, and contains no ads.

From the sources

The current UTC time, in every format a program can ask for, each one a single click to copy. No signup, no ads above the fold, and a free JSON API serving the same values. City names, IATA airport codes ( /jfk , /lhr ), timezone abbreviations ( /est ) and full IANA names ( /asia/kolkata ) all resolve to the offset, the identifier and the next DST change for that place. With JavaScript on, the first card becomes your own timezone as detected by Intl.DateTimeFormat().resolvedOptions().timeZone . Nothing is stored on our servers. worldtimeapi.org has been unreachable for long stretches, stranding ESP32, CircuitPython and Power BI projects that hard-coded it. Our API answers the same…from utctime.app

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
