Of course we knew who did what and when, that was not the problem and I never said it was. But the start date+time they entered for recurring series was converted to UTC on the client before it was sent to the server. So when it was decided that what they really wanted wasn't to run it "every 24 hours after the start date+time" but to run it on the exact time they entered every day, starting on the day they entered, the information about the exact time they had entered was gone.", all we had was that time converted to UTC. This meant we could not deduce the original time zone in which it was entered and thus could not deduce which DST schedule it should follow to keep it running at the same time every day.
