Frequently asked questions
Is my data uploaded?
No. Timestamp conversion runs entirely in your browser — nothing leaves your device.
Seconds or milliseconds?
Both: the tool auto-detects 10-digit (seconds) vs 13-digit (milliseconds) input and converts each way, always showing UTC and your local zone.
What timezone are results shown in?
Both: every decoded timestamp displays the UTC (ISO) time and your browser's local time, so timezone confusion is impossible.
