Unix Timestamp Converter

Convert Unix epoch times found in document metadata.

JavaScript is required for this interactive tool.Static Reference / Engine Logic:const val = input.value.trim(); const num = parseInt(val); if(isNaN(num)) { output.textContent = "Please enter a valid numeric Unix timestamp (seconds or milliseconds)."; return; } // Check if it's likely seconds or ms const date = num > 2000000000 ? new Date(num) : new Date(num * 1000); output.textContent = `UTC Time:\n${date.toUTCString()}\n\nLocal Time:\n${date.toString()}`;

How it works
