Frequently asked questions
Does this handle both seconds and milliseconds?
Yes. The converter detects whether your input is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly.
What timezone are the results shown in?
The 'Local' result uses your browser's timezone. UTC and ISO 8601 results are timezone-independent, which is what you should store or transmit.
