I would like to show the event timezone on the page that lists event details and the page that a registrant gets as confirmation after they register. Today my events are all in the same time zone but that will change in the future.
I can capture the time zone in a custom field but how do I get that custom field to show up
a) on event details pages
b) on registration confirmation pages
c) on event confirmation e-mails (I have read this page re confirmation e-mails which was very helpful, but I do not know how to access a custom field from within a smarty template)
Preferably the solution would not require changes that break upgrades.
