Frequently Asked Questions
What is Timestamp Converter used for?
Timestamp Converter transforms between Unix timestamps (epoch seconds or milliseconds) and human-readable dates. It helps debug API responses, analyze server logs, configure scheduled tasks, and convert timestamps between different formats and timezones.
What formats can it convert?
The tool accepts Unix timestamps in seconds or milliseconds (auto-detected based on magnitude), and ISO 8601 date strings. It outputs ISO 8601, UTC, local time, various date formats, Unix seconds and milliseconds, and includes timezone information.
How does the tool handle timezones?
The converter displays output in UTC, your local timezone, and ISO 8601 format. The local timezone is automatically detected from your browser settings. UTC is always shown for server-to-server communication where timezone ambiguity must be avoided.
When should I use seconds vs milliseconds timestamps?
Unix timestamps in seconds are used by most Linux systems, many APIs, and standard database systems. Millisecond timestamps are used by JavaScript (Date.getTime()), Java, and high-precision timing applications. The tool auto-detects which format you provided based on the value magnitude.
Is my data sent to a server?
No. All timestamp conversion happens locally in your browser using JavaScript's Date object. Your timestamps and date data stay completely private on your device.
What keyboard shortcuts are available?
Press Ctrl+Enter (or Cmd+Enter on Mac) while in the input field to quickly convert your timestamp. This enables rapid timestamp analysis during debugging or log review.
