I am looking for a global sequence generator in erlang cluster.<br>
<br>
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?<br>
<br>
I have read Time and time correction in Erlang (<a href="http://www.erlang.org/doc/apps/erts/time_correction.html" target="_blank">http://www.erlang.org/doc/apps/erts/time_correction.html</a>), but still have no conclusion.<br>
