Unix-Timestamp
Epoch ↔ Datum
Über dieses Tool
Convert between Unix timestamps and human-readable dates in any IANA timezone. Supports seconds (10-digit) and milliseconds (13-digit) timestamps. Useful for debugging logs, reading database records, scheduling cron jobs, and converting between systems that disagree on timezone or precision.
Privvert auto-detects whether your input is seconds or milliseconds, ISO 8601, or a free-form date. Live two-way conversion runs entirely in your browser.

Häufig gestellte Fragen
Like 2025-05-10T12:34:56Z - the international standard for date-times. The Z means UTC; +02:00 means UTC+2 (e.g. Copenhagen in summer).
Unix-original is seconds (10 digits). JavaScript and most newer systems use milliseconds (13 digits). The tool auto-detects based on length.
Almost always a timezone issue. A Unix timestamp has no timezone - it's an instant. The same instant displays as different dates in Copenhagen vs Honolulu.
Privvert uses 64-bit timestamps internally, so yes. The Y2038 problem is a 32-bit-system issue - modern languages and databases default to 64-bit.
The tool detects which one you pasted based on the magnitude - any value above 10^11 is treated as milliseconds. You can override the detection if your timestamps don't match the usual range.
The converted date shows both UTC and your local browser timezone side-by-side. For other zones, use the Time Zone tool with the converted UTC time as input.
