Re: pdm vs year 200

[Neil Palmer <neil@xxxxxxxxxxxxxx>]

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 !   ;-)
