Bug 143577

Version:           KPilot 4.6.0 (using KDE KDE 3.5.3)
Installed from:    Ubuntu Packages
OS:                Linux

I have used KOrganizer successfully for months.
Today for the first time I synced my newly acquired Treo 650 using KPilot.
Ordinary events transferred to the Treo OK.
Weekly recurring events transferred to the Treo OK.
The following recurring events transferred at the correct time but on the next day:
The last Tuesday evening of every month event showed up on the next Wednesday evening.
The 4th Tuesday evening of every month event showed up on the next Wednesday evening.
The 2nd Tuesday evening of every month event showed up on the next Wednesday evening.

Here's an example of the last Tuesday of every month event:
