We've come across a bit of a weird bug in the office. our office is closing for a week or so over christmas, and our admin staff sent a meeting request to everyone in the office to go from 5pm on the 23rd of December until we return to work at 8.30 on the 5th.

However there was some confusion, as if you look at the image below, the same meeting request is showing up with different start times for some people. While most people get the 5pm date, for others it shows up as an all day event! Staff have been planning their activities for the 23rd only to find out that their calendar is wrong and they are required to work.

With some investigation, we noticed that all of the people with the incorrect time own iPhones or iPads. So perhaps they accepted the meeting on their phones, and it has put the meeting in wrong?

There are people with the correct one that have iPhones, but perhaps they are on ios4 still, or perhaps they didn't accept the meeting request on their phone.

has anyone else come across this error at all? is there a fix?
