I'm getting more consistent results using Time.stamp instead of Time
From: https://github.com/fauna/cassandra/blob/master/lib/cassandra/long.rb
when NilClass, Time
# Time.stamp is 52 bytes, so we have 12 bytes of entropy left over
int = ((bytes || Time).stamp << 12) + rand(2**12)
I'll keep looking at this.
Thanks! :)
