Hallo All!

After playing around with two digit years I've discovered that at the zero
hour of January 1st 2069 coreutil's date application suddenly reverts back to
1969 as shown below;

-={ date --date='31 Dec 68 23:59:59 +0000' +'%F %T %z' }=-
2068-12-31 23:59:59 +0000

-={ date --date='1 Jan 69 00:00:00 +0000' +'%F %T %z' }=-
1969-01-01 00:00:00 +0000

Note that I am using for input the FTN two digit year with a corrected UTC
offset rather than the documented fts-4008 TZUTC flag which will produce an
error for all eastern timezones using proper date and time applications no
matter if two or four digit years.  I am not aware of any routine that will
properly compensate for this obvious flaw other than one I wrote specifically
to address the FTSC's obvious handicap when it comes to recognizing reality
and their part in the propagation of msg corruption.  :::tsk, tsk:::

Of further interest is the output of converting 2069 datetime stamps to
unixtime will produce negative seconds that will be repeated in reverse in
2070 since everything up to 2099 reverts back to the 1900's as shown below;

-={ date --date='1 Jan 69 00:00:01 +0000' +'%s' }=-
-31535999

-={ date --date='31 Dec 70 23:59:59 +0000' +'%s' }=-
31535999

Not good at all but not as bad as other examples of total two digit year
corruption caused by other datetime apps as well as differing OSes and their
associated problems with two digit years ... but I won't since they are really
depressing to read about to say the least.  Instead I will offer up that the
corrected datetime stamp at the start of this message was calculated by the
coreutils-8.32 date application as well as the FTN msgHeader's two digit year
which is NEVER used again for anything.  The proper solution would be to
finally get rid of it which should have happened at least in 2002 when it was
declared obsolete in use for digital communications.  If it isn't obvious to
you then I am guessing you're a member of the FTSC.  :::snicker:::
