  Search all
    'microsecond'

This brings back a bunch of hits, including Scott's 'gettimeofday'
wrapper.  In particular, look at the thread entitled ' Mcsec in
Timestamp, is it possible, '
http://archive.midrange.com/midrange-l/200102/threads.html#00778

In the spirit of trying to explain the underlying principles rather
than blindly posting code, if you are trying to measure something with
microsecond resolution you should read the thread in detail,
particularly postings by Barbara and Leif.  The returned value may be
unique, but it might not actually represent microseconds of elapsed
time.  The whole issue of hardware/software clock is another thing to
consider, and another set of searches will probably be needed.

The MI instruction MATMATR has some information on the hardware clock:

index.htm
Check the bit about the standard time format.  These MI instructions
can be used in RPG by calling them out of the C MI library.  The
reference there is the MI Library Reference, which I have in .pdf form
and therefore don't have a handy web reference for.

If you just want a unique stamp, any of the methods in the archives
should work for you, but you might consider a UUID for that instead.
It depends on what the business need is.
