Frequently asked questions
What is a Unix timestamp?
The number of seconds (or milliseconds) elapsed since 00:00:00 UTC on 1 January 1970 — the Unix epoch. It is a compact, timezone-independent way to represent a moment in time.
Seconds vs milliseconds — which does my system use?
Unix tools, PostgreSQL, and many APIs use seconds (10 digits in current era). JavaScript's Date.now() and Java's System.currentTimeMillis() use milliseconds (13 digits). The tool auto-detects which based on the length.
When does the Year 2038 problem hit?
On 19 January 2038, 32-bit signed Unix timestamps overflow. Systems using 64-bit timestamps are unaffected. Most modern systems migrated years ago, but legacy embedded devices and databases may still need updating.
What is ISO 8601?
An international standard for representing dates and times as text, e.g. 2026-05-25T14:30:00Z. Unambiguous across locales and the format used in JSON, RFC 3339, and most modern APIs.
