I added an event in Lightning next wednesday, 8:00. After sync, the event shows up in other calendars at 7:00. When I correct it in another calendar and sync, Lightning shows it at 9:00.
What a mess!

Doesn't work any more. I tried the candidate versions as indicated in other reviews, but Thunderbird tells me these XPI files are corrupt.
