Epoch ⇄ human date
Logs, databases, and APIs all store time as a Unix timestamp: the number of seconds since 1 January 1970. It is precise, unambiguous, and completely unreadable, and the moment you are debugging an incident you need it as a real date in two timezones at once. This converter goes both directions, handles seconds and milliseconds, shows local time alongside UTC, and keeps the current timestamp ticking for reference.
How to convert a Unix timestamp
- 1
Paste a timestamp or pick a date
Enter an epoch value, or enter a human date to convert the other way.
- 2
Read both timezones
The result is shown in your local timezone and in UTC so there is no ambiguity.
- 3
Copy the value you need
Take the formatted date or the numeric timestamp.
Good to know
- Seconds and milliseconds are both handled: a 10-digit value is seconds, a 13-digit value is milliseconds, and mixing them up is the single most common source of dates landing in 1970 or the year 55000.
- The live current timestamp is displayed for quick reference when you need "now" as an epoch value.
- UTC is shown alongside local time because logs are usually written in UTC while you are reading in local time.
- All conversion is done in the page using your device's own timezone settings.
What people use it for
- Turning a timestamp in a log line into a real date while investigating an incident
- Working out the epoch value for a specific cut-off date in a query
- Checking whether a stored value is in seconds or milliseconds
Frequently asked questions
Does it support milliseconds?+
Yes. Paste a value in seconds or milliseconds and it auto-detects which, then shows local, UTC, and ISO formats.
What's the live number at the top?+
That's the current Unix timestamp, ticking every second, with a one-click copy.
