There seems to be an issue with the setting of User Preferred TimeZone through the Web Client.
I am in Dublin, Ireland - which is GMT/BST. The correct time zone should be Europe/Dublin or Europe/London is equivalent as we observe the same daylight savings rules.
If I set my timezone to GMT +00:00 Britain, Ireland, Portugal through the Web Console -> Preferences tab, I would expect it to set my zimbraPrefTimeZoneId to be Europe/London. What I am seeing, however, is that it is getting set to UTC instead.
This is incorrect, as UTC does not have a daylight savings change.
Bizarrely, if I set my preference to GMT/UTC Coordinated Universal Time through the Web Console, it saves my preference as Europe/London
Has anyone else noticed similar issues ?
