Question

java’s System.nanoTime() seems to give a long: 1337203874231141000L
while python time.time() will give something like 1337203880.462787

how can i convert time.time()’s value to something match up to System.nanoTime()?

Answer 1

You can’t.

From the documentation:

This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time. The value returned represents nanoseconds since some fixed but arbitrary time (perhaps in the future, so values may be negative).
