Re: pdm vs year 2000

Neil  this can't be so. 
As your note reads dates from 1928 to 2027are ambigous .  The Century byte
does  nothing to help?  One would hope to see PDM consistent with the rules
for QCENTURY when this is being used as the determinate!

The AS/400 ''should'' have a single rule across all the system releases and
actions. No dual standards. After all multiple standards is how we got into
this mess.

 Well, before the PTF's the default PDM date range was 01/01/00 to 12/31/99
 for V3R2, and 01/01/40 to 12/31/39 for V3R7.
 The PTF cover letters (V3R2 SF40680/SF40685/SF40648, V3R7 
 SF38642/SF38508/ SF38513) state that the fix is to base the date range on
the
 new QCENTURY system value.  If QCENTURY=0 dates are 1928/01/01 to
2027/12/31,
 and if QCENTURY=1 the PDM date range is 1954/01/01 to 2053/12/31.
 Obviously the 6 digit date entry in PDM can only span 100 years, so between
 the two possible values for QCENTURY they cover the full date range that is
 presently supported on AS/400 (1928/01/01 to 2053/12/31).  Until further
 changes are made to OS/400 it can't handle dates from 2054 on - but I don't
 believe most of us will care too much about that - maybe our kids will have
 some concerns !   ;-)
