Thunderbird Calendar event - data vs visual discrepancy
A calendar event is booked at 10:30am. The pop-up window upon mouse-over shows the right time. However, the visual in the weekly view shows the event at 09.30am - why is that? In the picture, the current time line is at about 8:55am.

I created an event on the 29th and also the 30th set at 10am It displays as expected for the 29th and one hour early on the 30th.
On Sunday 30th March Daylight hours alter. In the UK the clocks go forward 1 hour at 1am on the last Sunday in March
So at 1am it suddenly becomes 2am. That means the calendar has entered the 10am event one hour early, so when clock goes forward one hour that should reset the event to 10am. Hopefully :)
But having explained where I think the logic is coming from, it's not exactly very helpful to see what appears to be an incorrect setting for future events on or after the 30th March.
I'll see if there has been some mention of this in a bug report etc.
