Error in from and to dates #73

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What happened?
Webical sees an end date different from iCal.

What steps will reproduce the problem?
1. Create an iCal event from 23.00 to 00.00 the same day
2. Webical will show it from 23.00 until 00.00 the next day

See screenshot for details.

.ics file will follow.

Did you only experience this with recurring events or with 'normal' events as 
well? I
don't have access to an iCal server ATM, will have to figure out a way to 
reproduce
this for myself...

This is not a recurring event. The RRULE you see is attached to the VTimeZone, 
not the VEvent.

You can reproduce it by just using the VEvent:

Basically the problem is:

Webical sees 20080216T000000 as at the *end* of the day, whereas iCal sees is 
as the *start* of the day.

This may be a problem in the ical4j DateTime class, but I did not dive into it.

You're absolutely right, I shouldn't try to figure out bugs so late in the 
evening :). 
I'll try to locate the source of the bug this weekend, shouldn't be to hard to 
find.
I don't think this lies with ical4j, it's more probable that I made a mistake 
somewhere.
