We're experiencing a problem with the zimbra web calendar when creating new appointments.

When a new appointment is saved is jumps back one hour from the desired time, I'll drag it or change the time inside the appointment and it will jump a head one hour from the desired time. It's only after the next drag that the appointment will stay at the correct time.

I've discovered that if I select "Show timezone list in appointment view:" and use advanced options to select my time zone, not Auto Timezone the appointment will stay at the correct time and not jump around.

I'm presently at day 15 of the 60 day trial using:
Release 4.0.3_GA_406.RHEL4_20061016143637 RHEL4 NETWORK edition

This behaviour is consistent with PCs using XP, Macs, RedHat and Ubunto and using Firefox 1.5-2.0, IE6-7 or Safari.

I've spent a few hours searching for the resolution.

Suggestions?
