Ross, I'm not derogating the use of sequential IDs but IIRC, the bloke had
a reason not to use a sequential id counter and wanted an alternative.
The uuid spec states that uuid should cater for time adjustments on the
local clock, hence, shouldn't be "vulnerable" (Of course, in the real

Maybe you should (re)read the thread on sequential IDS
Given an uuid string generated by AIX uuid_gen:
b6e7ce371f25.02.ac.1e.10.03.00.00.00
Under Windows "uuidgen.exe -x": 9b0a5933-e7b1-11d9-868e-000bcdf8b9a5
The first part(s) of these are time based, though it may be difficult (but
not impossible) to convert it back into a UV date/time format, the

One thing I forgot to mention about using system(99) is that, if for any
reason, the machines clock is adjusted backwards (eg. ntd), there is an
increased probability of duplicate numbers arising. With uuid, this should
be handled by the uuid implimentation.

To expand on this, you could switch to a time zone that doesn't observe
Daylight Saving Time before running the program.

Another possability is to implement the UUID generator for your OS. It's
gauranteed to be unique and you can also implement this scheme across
machines.
eg.
aix: sh -c "/.../uuid_gen"
linux: uuidgen
win: uuidgen.exe (win sdk command line tool) or
CreateObject("Scriptlet.TypeLib").Guid,38 (Win S

Why not put the time in the record and use a purely sequential key?

I need to generate a timebased sequential key which is independent of

time changes.
