Frequently Asked Questions

Find Quick Answers

What is Unix time?

Unix time (also known as POSIX time or epoch time) is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch), not counting leap seconds.

What's the difference between seconds, milliseconds, microseconds and nanoseconds?

Seconds is the base Unix timestamp. Milliseconds = seconds × 1000. Microseconds = seconds × 1,000,000. Nanoseconds = seconds × 1,000,000,000. Higher precision timestamps are used in high-performance computing and precise time measurements.

Does this tool handle timezones?

Yes, all conversions use your browser's local timezone for displaying human-readable dates. Timestamps are always in UTC (Coordinated Universal Time).

What is the maximum timestamp this tool can handle?

The tool can handle timestamps up to JavaScript's maximum safe integer (9,007,199,254,740,991), which corresponds to the year 285,616 AD for nanoseconds precision.
