[Zope] Menu of Timezones

[John Wheeler]

For an input form, I'd like to make a menu of time zones.

I saw in Appendix B: API Reference of the Zope Book that there already is a 
DateTime module function that returns a list of timezones, so I thought I 
could simply use <dtml-in> to go through the list, wrapping each 
sequence-item with <option></option>.

I tried every combination I could think of but got an error every time:

<dtml-in {below}>         Error Name     Error Value
=================         ==========     ===========
DateTime.Timezones        KeyError       DateTime.Timezones
Timezones                 KeyError       Timezones
"_.Timezones()"           AttributeError Timezones
"DateTime.Timezones()"    NameError      global name 'DateTime' is not 
defined
"_.DateTime.Timezones()"  AttributeError class DateTime has no attribute 
'Timezones'
"DateTime[Timezones]"     NameError      global name 'DateTime' is not 
defined
"_.DateTime[Timezones]"   NameError      global name 'Timezones' is not 
defined
"_.DateTime._Timezones()" SyntaxError    Line 2: "_Timezones" is an invalid 
attribute name because it starts with "_".

I even tried writing a python method using "from DateTime import Timezones" 
but got an ImportError: import of "Timezones" from "DateTime" is 
unauthorized.

Is it just not possible to access Timezones() through the web?  If I'd have 
to go to an external method, I'll just hardcode the timezones into the DTML 
method by hand.
