Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is the universal standard for representing time in programming, databases, and APIs because it is a single integer with no timezone ambiguity.
What is the difference between Unix seconds and milliseconds?
Most Unix timestamps are in seconds (10 digits, e.g. 1777621634). JavaScript and some APIs use milliseconds instead (13 digits, e.g. 1777621634000). If your timestamp looks 1000x too large, it is probably in milliseconds — divide by 1000 to get seconds.
Why do different apps show different times for the same timestamp?
Unix timestamps are timezone-neutral. When displayed, they are converted to local time based on your device's timezone setting. The same timestamp will show a different clock time in New York versus London versus Mumbai — but they all represent the same instant.
What is ISO 8601 format?
ISO 8601 is the international standard for date/time strings, formatted as YYYY-MM-DDTHH:MM:SS.sssZ (e.g. 2026-05-01T07:47:14.000Z). The Z means UTC. This format is widely used in APIs, databases, and data interchange because it is unambiguous and sortable.
