Mcsec in Timestamp, is it possible

Title: Mcsec in Timestamp, is it possible

There is a MI function you can call the generates a universal unique id.

d GenUUID         pr                  extproc('_GENUUID')             
d  UUID_Template                  *   value                           
                                                                      
d UUID_Template   ds                                                  
d  UtBytPrv                     10u 0 Inz(%size(UUID_Template))       
d  UtBytAvl                     10u 0                                 
d                                8a   Inz(*allx'00')                  
d  UUID                         16a                                   

This works across multiple system.  We have 3 AS400's.  (170, 400 & 720)  Each generated 1,000,000 UUID and timestamps.  These files were combined to one.  The UUID's were unique.  We did have duplicate time stamps from different systems.  (only a couple)  The time stamps were to the milli-second. 

NEVER rely on a timestamp to be unique.

FYI,

OBTAINING THE SYSTEM TIME IN MILLISECONDS
There are times when it can be handy to obtain the system time with
milliseconds - for example, when you want to create a unique
identifier for data transfers.
