Navigating Time in Code
Developers constantly juggle time formats. Backend logs often use Epoch Seconds (`1609459200`), while frontend JavaScript uses Milliseconds (`1609459200000`). Mistaking one for the other results in persistent bugs (like dates appearing in 1970 or 50,000 AD).
This converter intelligently detects your input format and provides all equivalent representations instantly.

Standard Unix time uses **Seconds** (10 digits). JavaScript and some modern systems use **Milliseconds** (13 digits) for higher precision. Our tool detects this automatically.
The "Year 2038 problem" affects systems using signed 32-bit integers to store time, which will overflow. Most modern systems (64-bit) are already safe for billions of years.
