TimeZone hover

I built a tiny fix for time-zone friction. What it does - Hover any time string on any website to see your local time + zone (e.g., Asia/Tokyo) - One-click copy in 12-hour / 24-hour / ISO 8601 - Options UI; Pro adds default format, per-site enable/disable, and import/export Under the hood - Chrome MV3: background service worker + content script - Permissions: `storage` only (to save preferences) - No tracking, no external calls for tooltips Links - Chrome Web Store: - Landing & screenshots: https://doooooraku.github.io/Time-Zone Feedback I’m looking…

TimeZone hover launched on October 21, 2025 with 9 votes, #1,657 of 8,178 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 1 year on.

What it does

Tired of copy-pasting times into Google? Time-Zone Hover instantly converts any time string on any website to your local time zone—just by hovering. It's non-destructive, privacy-first (works 100% offline), and lets you one-click copy in ISO/12h/24h formats.

In the maker’s words, at launch

    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…

  • I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  • Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
