Frequently asked questions

What is a Unix timestamp?
A Unix timestamp counts seconds since January 1, 1970 (UTC). It's used across programming languages and databases to represent moments in time as a single number.
How do I know if my timestamp is in seconds or milliseconds?
10-digit timestamps are in seconds (standard Unix). 13-digit timestamps are in milliseconds (used by JavaScript, Java). This tool auto-detects the format.
Why do the timezone times look different?
The same moment in time is displayed differently depending on timezone due to UTC offsets and daylight saving time rules. The timestamp itself is always UTC-based.
Is my data stored anywhere?
No. All conversion happens in your browser using JavaScript. No data is sent to any server.
What formats are supported?
ISO 8601, RFC 2822, Unix seconds, Unix milliseconds, relative time (e.g. "3 hours ago"), and local date/time in 10 common timezones.
