Timestamp Converter
Convert a date and time between ISO 8601, UTC, local time, and Unix seconds and milliseconds, with the weekday and time zone offset shown as well.
How to use
- Paste a date such as an ISO 8601 string.
- Read UTC, ISO, and local lines.
- Copy the format you need.
The timestamp converter reads a date and time and writes it in the formats developers actually use: ISO 8601 for APIs and logs, UTC for storage, local time for people, and Unix seconds or milliseconds for timestamps.
Output
Paste or type something above.
Questions about timestamp converter
- Which formats can I paste?
- ISO 8601, a readable date and time, and RFC 2822 style values all parse.
- Which format should I store?
- Store UTC and an ISO 8601 string. Convert to local time only when you show it to a person, which keeps daylight saving out of your data.
- Why did parsing fail?
- The value was not a recognisable date. An ISO 8601 string with a timezone is the least ambiguous input.
