Часто задаваемые вопросы о конвертации Timestamp

Is my timestamp in seconds or milliseconds?

Count the digits: roughly 10 digits means seconds, 13 means milliseconds. A milliseconds value read as seconds lands around 1970 × 1000 years in the future.

Why does the date look one day off?

Epoch values are UTC. Near midnight, your local zone moves the calendar date, so check both readings the page shows.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the Human-readable date and time.

What should I check before using the result?

Open the Human-readable date and time in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

Is Unix Timestamp Converter free?
