[erlang-questions] Does erlang:now() guarantee that subsequent calls to this BIF returns continuously increasing values even in erlang cluster?

Hi, dear list,
I am looking for a global sequence generator in erlang cluster.
I think erlang:now() is promising, because it is fast enough and “also guarantees that subsequent calls to this BIF returns continuously increasing values”. But I am not quite sure whether this guarantee also works for erlang cluster which have several nodes running on different servers?
I have read Time and time correction in Erlang (http://www.erlang.org/doc/apps/erts/time_correction.html), but still have no conclusion.
