Apologies if this is documented somewhere, but I have literally spent hours looking for an answer to this or workaround, but I'm more and more convinced it's a bug. As a result, I'm going to write this post as a bug report more than a general thread. Description of problem: Recurring all day events in iCal format should end on correct day of month and not include time in RRULE Version-Release number of selected component: Whatever version of code that was running on Thu Jan 2 19:00:00 UTC 2014 How reproducible: Always Steps to Reproduce: 1. Login and navigate to http://www.localendar.com/elsie 2. Click on "Add Event" from the local navigation on the left. 3. Enter an event title in the "Title" text field. For example: "Test 00". 4. Select the "All Day Event" radio button in the "Time" input field. 5. Expand the "This event repeats" section. 6. Select the "Repeat Daily (until date above)" radio button. 7. Modify the "Repeat Until" drop-down to be some date in the future. For example: "January 1 2014". 8. Press the "Save" button. 9. Test 1: View public web interface: http://www.localendar.com/public/[username] 10. Test 2: View "RRULE" field of event created: curl -s http://www.localendar.com/public/[username]?style=X2 | grep ^RRULE Actual results: Test 1: Repeated event matches specification Test 2: The "UNTIL" attribute of the RRULE field is an additional day out (02 instead of 01, in this case) and includes a time: $ curl -s http://www.localendar.com/public/bdperkin?style=X2 | grep ^RRULE RRULE:FREQ=WEEKLY;UNTIL=20140102T190000Z;BYDAY=SU,MO,TU,WE,TH,FR,SA Expected results: Test 1: Repeated event matches specification Test 2: The "UNTIL" attribute of the RRULE field is the expected end day and does NOT include a time: $ curl -s http://www.localendar.com/public/bdperkin?style=X2 | grep ^RRULE RRULE:FREQ=WEEKLY;UNTIL=20140101;BYDAY=SU,MO,TU,WE,TH,FR,SA Additional info: This was found while using a public calendar as a URL through Google Calendar. The repeated all-day events result in appearing as running one additional day in Google Calendar. Manually modifying the ics and importing it works, therefore, I believe that if this change is made on localendar server-side, this fix should "just work". |

In supporting iCal, we've tried testing with as many firms as possible, including Apple, Google, Yahoo, Microsoft (Outlook) and others. The spec for the iCal RRULE is clear: The UNTIL rule part defines a date-time value which bounds the recurrence rule in an inclusive manner http://www.ietf.org/rfc/rfc2445.txt (emphasis mine) Your example bug actually parses fine in Outlook, for example. In general, the spec encourages as much specificity as possible, and does not want to leave Date parsing open to implementation (which is what happens when you leave out a time). Unfortunately, Google isn't perfect  They've decided to only support 1 possible format. Again, excerpted from the spec:"...this date or date-time becomes the last instance of the recurrence" (emphasis mine again) We will look at the latest version of the products we test with and see if they can "get by" with the more minimal specification. After all, Google is popular and we are feel compelled to work with them, even if they don't have the best implementation. ---------------------------------------- Marc Higgins Support Associate, localendar.com Follow us on Twitter! http://www.twitter.com/localendar_news |
