About this tool
Convert Unix timestamps to human-readable dates (local, UTC and ISO 8601) and back, with a live current-timestamp clock. Detects seconds versus milliseconds automatically. A daily companion for log digging and API debugging.
Seconds or milliseconds?
Unix time is classically in seconds; JavaScript uses milliseconds. Large values are treated as milliseconds automatically.
What is ISO 8601?
The international date format - unambiguous and sortable, ideal for APIs and logs.
