Can I get value of Curren time from miliseconds value

I have a value in miliseconds 1601626934449

Which generated via https://docs.oracle.com/javase/7/docs/api/java/lang/System.html#currentTimeMillis()

but can I somehow be able to get time in human readable format, or in brief I need to be able to know what the value in miliseconds 1601626934449 is ?
