Bob,

I am not aware of any OS/400 fixed window of 1970 to 2069.  There is
a fixed window of Thu Jan 1 00:00:00 1970 to Tue Jan 19 03:14:07 2038
for C functions that use the industry C definitions of time (namely
a long integer representing the number of seconds since Jan 1 1970).
As ILE C defines a long integer as 4-bytes, that causes a wrap in time
come Jan 19 2038.  Is it possible this is what they are referring to?
Or perhaps "IBM is inconsistent" is referring to platform other than
AS/400?

In any case, I would recommend the fixed window of 0 to 9999 (that is,
use 4-digit years) wherever possible.
