Ah it gets rid of the non-time related bits. Below is a description of the formatting

* id is composed of: * time - 41 bits (millisecond precision w/ a custom epoch gives us 69 years) * configured machine id - 10 bits - gives us up to 1024 machines * sequence number - 12 bits - rolls over every 4096 per machine (with protection to avoid rollover in the same ms)

thanks :)
