RE: Mcsec in Timestamp, is it possible, THANKS A LOT!

Cool!

It works! Thak You!

The point is that I use timestamp as a unique key for of the financial
transaccion. Everything was ok in 740, but I started to get problems (more
than one transaccion were iniciated in the same millisecond) after switching
to our new 840 with 24 CPU. It's OK now with microsenconds included.

Best regards,

Dmitri

Actually, that program only goes down to milliseconds...   I never
needed microseconds on the AS/400....  though UNIX/POSIX does it with
the gettimeofday() function.  

(10 minutes later)  In fact, here's an example:

     H BNDDIR('QC2LE')

     D gettimeofday    PR                  ExtProc('gettimeofday')
     D   timeval                      8A
     D   timezone                     8A

     D GetTimeZone     PR             5A

     D timeval         DS
     D   tv_secs                     10I 0
     D   tv_usecs                    10I 0

     D timezone        DS
     D   tzDir                        1A
     D   tzHour                       2S 0
     D   tzFrac                       2S 0

     D Junk            S              8A
     D Epoch           S               Z
INZ(z'1970-01-01-00.00.00.000000')
     D Current         S               Z

     c                   callp     gettimeofday(timeval: junk)

     c                   endif

      ** show it.
