My brother's birthday is on November 22. Once every 7 years, on
average, his birthday falls on Thanksgiving. I was curious about when
exactly that would occur in the future so I did something like this in
the bash shell on a GNU Linux system:
for year in $(seq 2008 2060) ; do date -d 11/22/$year | grep Thu ; done
And if you try it, you'll see what happens -- it fails starting in 2038.
It also fails if you go back before 1970.
With a 64-bit Linux OS it does not fail before 1970 nor after 2038. I had
no idea that the 2038 problem was limited to 32-bit systems. Is that
true? I did know that the limit was of 2^31 seconds frm 1970 to 2038, so
I guess it makes sense that it isn't a problem in 64-bit systems.
