I am reminded of the US DST changes back in the 2000s: there was all sorts of drama because a lot of software is written in the US, and there was much 'computerization' in the 1990s, but US coders had never personally experienced a DST rule change during that time period, so any change needed a reboot to pick up the new rules.
That drama led to (e.g.) periodic dynamic checking of /etc/localtime on various Unix-y system.
Sometimes you don't realize that things can be improved until you experience situations in which they currently suck.
