Sooo, when year 2040 comes around, the program will see it as 1940?

Subject:        IBM Y2K Readiness

Just received an interesting response from IBM regarding their Year 2000
readiness.  We are using their Fax/400 product and they claim it to be
Y2K ready.  I questioned this in an e-mail to them since I had noticed a
log file (QAFFTLOG, which is an important file to us) had a 6 digit date
in it (in the format YYMMDD) and did not have a century code to go along
with it.  Following is the response I received from IBM:

It sounds like they're telling me that they don't intend to change the
date from a 6 digit date and it's up to me to use the date "window"
technique to determine the correct year.  Does anyone else besides me
feel that that's not right?  They could essentially tell me that any IBM
system database file is Y2K ready as long as it has a 2 digit year.

What do you think?
