What is a Unix Timestamp?
A Unix timestamp (or Epoch time) is a system for describing a point in time. It is the number of seconds that have elapsed since the Unix epoch, minus leap seconds. The Unix epoch is 00:00:00 UTC on 1 January 1970.
Because it is a single number, it is very easy to store, transfer, and compare timestamps in computing environments. In many systems (like JavaScript), timestamps are tracked in milliseconds instead of seconds, which is why our tool provides both.
ISO 8601 and RFC 2822 Formats
While timestamps are great for computers, human-readable strings are needed for logging and displays. Standardized formats ensure global compatibility:
- ISO 8601: An international standard covering the exchange of date- and time-related data. It looks like
YYYY-MM-DDTHH:mm:ss.sssZ. It resolves ambiguity by putting the largest temporal term (the year) first, down to the smallest (seconds). - RFC 2822: The standard format for dates in email and HTTP headers. It looks like
Wed, 08 Mar 2023 00:00:00 +0000.
Client-Side Processing
This Timestamp Converter runs entirely within your web browser. When you input a date or click "Now", all calculations and conversions are performed locally using standard JavaScript Date APIs. No data is sent to external servers, making it fast, private, and fully functional offline.
