Summary	0002969: Week view shows wrong start date at week that DST change occurs
Description	Hi. I'm trying to implement SOGo, but there is one thing that's breaking the job. The view of calendar on a week that occurs a daylight saving time change gets wrong. In Brazil, it's happening in week 43 (my Timezone is America/Sao_Paulo). Just as i open the calendar page on that week, i see that this week starts on saturday (not sunday as the others). And if i try next week, it just does not work. If i try previous week, it takes me to the 41 week.
Steps To Reproduce	Change Timezone on server to America/Sao_Paulo Change client timezone to America/Sao_Paulo go to 43 week it shows Saturday at the beginning of week (it should be Sunday) go forward (next): it stays at 43 go backward (previous): it goes to 41
Additional Information	i already have this problem with a php webclient. the function next().day on a day that a DST change occurs return the same day on the first call, just on the second it goes to new day (one day ends at 11 PM and the other begins at 11PM).
Tags	No tags attached.

ftristao 2014-10-30 12:47 reporter ~0007639	as a workaround, i did make a change on my timezone. Since the problem occurs when the DST starts at 0h, i change it to 1h and, this way, it works fine.

ftristao 2015-01-12 12:05 reporter ~0008054	Yes. The issue is just the same. The week when a DST occurs is wrong and so the effects on the next and previous bottons.
