European friends, prepare for the pain of time zone rule changes announced with too little notice. See the proposed directive at the end of ec.europa.eu/commission/prio… When the US did this in 2007, most calendar software bound timezone rules to events when the events were created.

🕒 We are proposing to end seasonal clock changes in Europe in 2019. The last mandatory change to summertime would take place on Sunday 31 March 2019. #SOTEU #ClockChange #EfficientEU

End seasonal clock changes

The proposal seeks to ensure that any changes are made in a coordinated way between neighbouring countries so as to safeguard the proper functioning of the internal market and avoid fragmentation.

Maybe things are better now, but I'm not optimistic, especially when multiple calendar programs are involved. Think about recurring events. That "every Monday at 10am" meeting that you've already created could be "every Monday at 10am by the old timezone rules".

Six months notice seems like too little for the timezone database to be patched, all operating systems to ship that update, everybody to get that update, and then complete all the recurring meetings or cross-country video meetings scheduled prior to the update.
