Epoch Time
Unix Epoch Timestamp
The number of seconds elapsed since January 1, 1970 UTC, used as a universal time reference.
รายละเอียดทางเทคนิค
Epoch Time represents time as a single integer, making it timezone-independent and ideal for computation. The 32-bit signed integer limit (2,147,483,647) will overflow on January 19, 2038 (the Y2038 problem). 64-bit timestamps extend the range to ±292 billion years. JavaScript's Date.now() returns milliseconds since epoch, while Unix timestamps use seconds. Converting between timezones is a display concern only — the underlying epoch value is always UTC.
ตัวอย่าง
```javascript // Current epoch timestamp const epochMs = Date.now(); // milliseconds const epochSec = Math.floor(Date.now() / 1000); // seconds // Convert epoch to human-readable new Date(1709913600000).toISOString(); // → '2024-03-08T16:00:00.000Z' ```
