Show HN: Epoch.place – A modern, sensible Unix timestamp tool (opens in new tab)

Any time I need to convert a date to or from Unix epoch timestamps, I find something on Google and I’m pretty disappointed with the experience. Every single option on the first page of results uses six or more form fields to enter the date and time, and they use discrete forms to go in each direction. Even the one available on Omni Calculator isn’t so great.

And spending a lot of my day in JavaScript, I always have chop off some digits by hand before any of these tools work, since they don’t detect when values are in milliseconds.

I made epoch.place [1] to try to modernize things a bit. It’s open source [2], and features include:

- Modern natural language date parsing - Automatic detection of Unix timestamps in seconds and milliseconds, with overrides - Multiple output formats always available - Click-to-copy any resulting values - Linkable results - Realtime output of the current time in all formats, and the delta between your input and now

Simple, straightforward, no frills. The page should load in about a tenth of a second, so you can get in and get out.

It uses Chrono [3] for parsing, and runs entirely client side with no cookies, tracking, ads, or dependencies (other than Chrono which is being loaded from jsDelivr).

Mobile support is still a WIP, but I hope this app makes the task of dealing with timestamps a little bit easier.
