474218 - Invite/Attendees screen - Free/busy interval is shown incorrectly at 100% zoom

Status: VERIFIED DUPLICATE of bug 411169

(Calendar :: Calendar Frontend, defect)

Description

[Srikanth]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5
Build Identifier: Ligntning 0.9, Thunderbird version 2.0.0.19 (20081209)

When I try to schedule an event for a duration of 30 minutes, in the 'Invite attendees' screen at 100% zoom, my free/busy information for other meetings in my calendar (or for that matter of other invitees) and are of 30 minutes duration are shown as of 1 hour duration.

This is misleading and gives an impression that there's a schedule conflict.

However, when I increase the zoom to 200% the durations are shown correctly as 30 minutes. I believe it should be shown correctly even for 100% zoom.



Reproducible: Always

Steps to Reproduce:
1. With configuration as mentioned under 'Additional Information', create 'New Event'
2. Click on 'Invite Attendees' (Ensure that you already have another event in your calendar of duration 30 minutes, say a meeting from 9:30am to 10am)
3. Ensure that you are at 100% zoom
4. The previously accepted meeting from 9:30am to 10am is shown in free/busy as being from 9am to 10am. It gets worse if the meeting was from 9:30am to 10:30am, then free/busy shows your calendar as busy from 9am to 11am.
5. Increase the zoom till you see the right free/busy info (I saw it at 200% zoom, others at 400% zoom)
Actual Results:  
At 100% zoom, an already accepted meeting in your calendar from 9:30am to 10:30am is shown in the 'Invite attendees' screen's as being busy from 9am to 11am

Expected Results:  
It should have shown the busy info correctly from 9:30am to 10:30am at 100% zoom (and not at higher levels of zoom)

My lightning is configured as follows:

- Week starts on Sunday
- Work week includes all days except Sunday
- Day starts at midnight and ends at midnight and the view is configured to show 5 hours at a time
- For multi week view, default weeks to show is 6 weeks and previous weeks to show is none
- Default event length is 15 minutes
- Default snooze length is 5 minutes
- Refresh calendars every 5 minutes

Needs investigation for 1.0

The cause of this is that only full blocks are shown. With 100% zoom, the blocklength is one hour. In that hour falls the half-hour meeting, so the hour is shown as busy. With the event of 9.30 to 10.30, both hours (9-10 and 10-11) are shown as busy.

In this respect, I felt that the way Outlook represents the free/busy info is more intuitive. There's no zoom required and all the information is available in the same screen without having to do anything.
