US daylight savings is today (March 12th). EU daylight savings is two weeks from now (26. March).
If you happen to have meetings with international folks, they will be wrong and everyone will be confused and late/early for the next week or two. Plan accordingly, be kind if someone no-shows.
Don't debate the concept of daylight savings in my replies please, like it or not it's happening nowish.
Regular reminder that if you run systems in multiple time zones, do not use anything but UTC for your company. There are people like me who have jobs where exact time is needed and hate having to deal with mismatched timezones.
