Convert any date to Discord timestamp format instantly with 9 format options and one-click copy.
zhengguge06 · V2EX
做了一个 Discord 时间戳转换器,再也不用算 Unix 了 # 经常在 Discord 里组织活动的人都知道,定好活动时间还不算完 怎么让不同时区的人都能看懂才是问题。直接写“晚上 8 点”,总有人按自己的时区理解;让大家手动换算时区又很麻烦。 我试用了不少市面上的同类工具后,根据自己的实际需求做了一个小工具:[Timestamp Rocks]( https://timestamp.rocks/) 选择日期、时间和 IANA 时区,工具就会自动生成 Discord 支持的 9 种时间戳格式。你只需一键复制并粘贴到频道里,Discord 就会按照每个人的本地时区和语言显示同一个时间。  ## 为什么还要造这个轮子? 我试过的同类工具里,主要遇到了两个问题: 1. 有些工具只展示几种常用格式。我经常使用“相对时间”格式,例如显示“3 小时后”,但并不是每个工具都能方便地生成。 2. 夏令时处理几乎都翻车。大部分工具拿"今天的 UTC 偏移"去算未来的日期——3

Track time, manage projects, and create invoices all in one app for freelancers.
u/AstronomerGreedy · Reddit
I got tired of juggling 4 different tools to run my freelance business, so I built one that does it all. I'm a freelancer, and for a couple of years my business ran on duct tape: one app for time tracking, another for invoicing, a separate e-sign tool for contracts, and a spreadsheet to check if I was actually making money that month. So over the past few months I built Workey (React + TypeScript + Supabase) — one dashboard for the whole "get paid" loop: - Time trackin

Built a When2meet alternative that actually works on mobile — looking for feedback Hey all — I got tired of the usual group-scheduling mess (When2meet's mobile UX, timezone dropdowns that cap out around a dozen zones, tools that want you to connect your Google Calendar just to find a time to hang out), so I built FreeToMeet . What it does: create a poll, share one link, everyone marks their availability by dragging across a grid (actually works with touch, not tap-per-cell), and you get a

Get daily summaries of your podcasts with TLDRs and key takeaways.

PodTLDR.fm — I follow 12 podcasts and listen to none of them, so I built the thing that reads them for me I follow about a dozen long-form podcasts - Acquired, Lex, Hardcore History - and I was permanently 30+ episodes behind. Every new 3-hour drop just added to the guilt pile. I didn't want to listen to them. I wanted to have heard them. So: PodTLDR.fm. Add a podcast, and every time it drops an episode we transcribe it, summarize it, and email you the TLDR by morning - the one-line point,

Calculate your Bazi birth chart with true-solar-time correction and Five Elements analysis.
u/JianJi-Bazi-Creator · Reddit
I spent over 2,000 USD on AI tokens turning my childhood hobby (Chinese astrology) into a free web tool Hey everyone — I built www.jianji.uk/rd , a free Bazi (Four Pillars of Destiny) reading tool. Sharing it here as my first "real" side project. Quick backstory: I grew up fascinated by the Yi Jing and Chinese destiny studies. When I first started working, I used to cast charts for colleagues and friends — sometimes with uncanny accuracy. One time, using a classical method from the San Min
