iCal appointments showing wrong time

I recently upgraded to OS 10.9 Mavericks and today I noticed that new iCal appointments coming in from WebEx are showing up 1 hour later than they should. It's almost like it thinks I'm in a different TZ or my PST/PDT calculation is off. I've double checked this and it's consistent. Here is a snapshot:

WebEx has confirmed that it's their problem. I got a call from their Engineering dept last week. Person apologized and said they were working on it....however, did NOT give a date for the fix. I got the generic..."in an upcoming release". When I pushed for a date, there was just apologies.


Bad on WebEx



Lotus Notes....IBM seems to think it's Apple's fault; Apple seems to think it's IBM's fault. No movement here. I actually discussed with an Admin running a lotus notes installation and they think it's IBM's bad.


that's the latest I have

Working with IBM we've confirmed its an Apple issue. (bug in the parsing of RRULE entries in ical file) Apple is aware of it, but of course they don't provide any way for you to track their progress or have them let you know when they are resolving it, but "Its currently under investigation"


so your options are to either write something to munge the ics files before they are ingested, or use the lotus notes client (just kidding, thats not really a sane option)


what I found interesting is that BusyCal also demonstrated the bug... so it must be something in the libraries.

I am also seeing the same issue of the wrong time being recorded to my calendar working with outlook. The problem also occurs upon accepting the invite on any of my idevices, iPhone, iPad. If the meeting is created in Outlook at 3pm EST, upon acceptance the meeting will show as 3pm EST - instead of 1pm MST (my timeline). So for me the issue is occurring on all my Mac running maverick as well as iPhone and iPad running iOS 7.1.1.

I am experiencing the same issue. When I receive a calendar invite from someone using Lotus Notes, the time is coded as "Pacific Daylight Time" and shows up on my iCal as an hour different from the actual intended time (for me, "Pacific Standard Time"). This is a huge pain for me.


Thanks to this thread, I was able to successfully edit (using Text Edit) a recent invite to remove the offending RRULE entries. The invite then processed correctly in iCal. Kudos to everyone who explained the problem and offered an interim fix.


I really hope that Apple fixes this seemingly obvious problem. It's ridiculous to have to manually edit each new calendar invite to fix the time zone issue.

Hi,


this fix also works for me, also this line is showing up in /var/log/system.log when importing the original file (from Notes):


[com.apple.calendar.store.log.ICS] [Unrecognized value in RRULE FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=3, (BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=3)]


Any news on this issue/an official fix?


thx!

Hello, I'm a Filemaker developer and have written a script to export .ics files from my solution...


I was having this same intermittent issue, and then noticed that if iCal is open and running and you pass midnight... 00:00, then iCal begins to write calendar entries 1 hour infront of the time settings on the .ics file!


I restarted iCal and the problem went away!!!


Do you chaps regularly sleep your laptops / machines with iCal open? if so this could be the problem.


Hope this helps.

2015 and the problem persists (Yosemite 10.10). Screwd up an important meeting today because of this.

Googled and found many problem descriptions but no solution.

It used to be that apple made our computer life easier. Not these days. Being a mac user for 30 years I am now thinking about a switch.

Since after Snow Leopard I experience a loss of productivity.

I'm feeling the same way. Between the issue of meetings showing up one hour late and the impossibility of synching gmail without frustration, and the ever-increasing time lost to the spinning wheel of death.. I'm just about over Mac -- also after 30 years. You'd think Apple might be concerned about loyals like us -- but apparently not.

I do not believe ticking the time zone support box fixes the problem, on my computer it has been enabled all the time, and I have the same issue with Lotus Notes invitations as a lot of you have described. It is super annoying.

I have a feeling the problem started on the day we switched to summer time.

I have the same issue, but it is wider. Some appointments (not all) coming in from another Apple user (on 10.9, IIRC, possibly 10.10) and from my HMO, in .ICS format are showing up wrong in iCal.

Sometimes, they are an hour off, more commonly, they're some random date in the past, sometimes a day before, sometimes several years ( ! ) before the real date.
I haven't been able to find any consistency in terms of which appointments get mangled and by what time difference.

The only "fix" is manually copy the event over to the correct date. Of course, if it's an event I was expecting so just accept the invite without examining the date/time closely, I now don't even know where it ended up on the calendar and have to search for it... Yuck.


I'm on 10.8.5 . Never had those issues before 10.8, and my calendar has 17 years of events in it.
