# Creating and getting a timestamp from the UUID
uuid = SimpleUUID::UUID.new => <UUID#2278170300  .... >

# Given raw bytes from a source such as cassandra (using bytes from an existing UUID as an example)
bytes = SimpleUUID::UUID.new.bytes
SimpleUUID::UUID.to_time(bytes) => Thu Aug 18 19:15:16 -0400 2011
