@matigo Yep. But sometimes they are darn annoying, like the calendar bug I am having at the moment.
The customer, for whom I do consultation work, uses Office (because they are a bank) while we use Google stuff. When they send us a calendar invitation, it has the start and end times in daylight savings time (EEST) already now when it is not in use. This applies to both one-off events as well as for recurring events. The one-off events they are at the right time in our calendars (which converts them all to UTC), but the recurring events are one hour earlier in our calendars. Also, if they make any changes to the event, we do get the update email but the event start and end times might not get updated. It is always ”funny” to try to guess when the events start.
