How to Generate Visitor ID/UUID

If not, my thought was to do something similar to what tcllib uuid is doing:

 

 

Append the following together:

 

clock seconds Timestamp

 

clock clicks system incrementing counter

 

pid additional entropy

 

server_addr get some spatial uniqueness

 

client_addr add some more spatial uniqueness

 

 

Then md5 this all, and convert the result to a UUID format.
