[[[most computer programs used the last two digits to represent a four-digit year]]]

We converted everything from a 2 digit year to a 4 digit year format.

Now a lot of places have converted back to two digits. But 2020 is confounding things a bit.
I still have one .exe program that I have to turn the clock back to run. No access to the source code to correct.
