Context
As an active user of Grist, I use it to manage a dense schedule in my working day (from 8am to 5pm without pause). Grist is great for this, since you can create rows directly from the calendar widget
Problem
Since I’m working in France, we have summer time changing hours : on the 30th of March, at 2am, it’ll be 3am instead.
However, when I create an event from 9:30am to 10:30am, it displays it as it would be before the change, so graphically it shows 10:30 am to 11:30 am
Solution
Correcting the calendar widget to show events correctly despite this changing hour process
