Current Unix Timestamp & Quick Date Converter
A live epoch clock up top, plus two boxes for date ↔ seconds or milliseconds
A lightweight timestamp converter with just two boxes. The current Unix timestamp sits at the top of the screen and ticks over every second, so when all you need is "what's the epoch time right now," it's already there waiting. Type a number and it works out the unit for you — 10 digits reads as seconds, 13 as milliseconds — and returns your local time, UTC, and ISO format. Go the other way by picking a date and copy the seconds or milliseconds value straight out. If you need microseconds, nanoseconds, or relative time like "3 hours from now," use the Epoch Precision Converter instead.

FAQ
- What is a Unix timestamp?
- It's the number of seconds (or milliseconds) elapsed since January 1, 1970, 00:00:00 UTC — the standard way of handling time in programming.
- How do I tell seconds from milliseconds?
- A 10-digit value is usually seconds, and a 13-digit value is milliseconds. The tool detects this automatically, but you can also set it manually.
- How are time zones handled?
- The result is shown in both your local time (based on your browser) and UTC.
