Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp (also known as Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is widely used in computing to represent dates and times as a single number.

What is ISO 8601 format?

ISO 8601 is an international standard for representing dates and times. The format looks like "2024-01-15T14:30:00Z" where T separates the date and time, and Z indicates UTC timezone. It can also include timezone offsets like "+05:30" for India Standard Time.

What is the difference between seconds and milliseconds?

Unix timestamps in seconds are typically 10 digits long (e.g., 1609459200), while millisecond timestamps are 13 digits long (e.g., 1609459200000). JavaScript's Date.now() returns milliseconds, while many backend systems and databases use seconds.

What is the Year 2038 problem?

The Year 2038 problem (Y2K38) occurs because 32-bit systems store Unix timestamps as signed integers, which will overflow on January 19, 2038, at 03:14:07 UTC (timestamp 2147483647). Modern 64-bit systems can handle timestamps until approximately the year 292 billion.

Is my data secure?

Yes, absolutely. All conversions are performed entirely in your browser using client-side JavaScript. No data is sent to any server, ensuring complete privacy.
