From /@@dateandtime-controlpanel the default portal timezone can be set, but the list is limited.
I'd like to set the time to my very own city, not the next largest city (in the same timezone).
Is there a way to set this timezone, maybe from the ZMI or a XML file in my policy package?
The lists of timezones in the control panel are from two vocabularies:
(see class IDateAndTimeSchema in Products.CMFPlone.interfaces.controlpanel)
The vocabularies are defined in plone/app/vocabularies/configure.zcml
I would like to set plone.app.vocabularies.CommonTimezones to plone.app.vocabularies.Timezones
without modifying the source code of plone.app.vocabularies. How?
