Rails - Aug 2005 - datetime_select with timezones

I was looking over the datetime_select helpers in the Rails api page
today and I didn''t see anything that would allow me to build a
datetime field with timezone offset. I would like to be able to select
EDT, CDT, GMT etc from a list but offsets of -5, -6 , 0 will work. Is
there support for this in edge Rails or do I have to do this the hard
way?
