How to change the time zone on a TimeWithZone object?

I'm working on an app which has its config.time_zone = 'Kolkata' (which is UTC +5:30), I'm trying to save the time for a particular object in EST/EDT (UTC -5:00/-4:00) from the ActiveAdmin panel.

Since it involves daylight savings, I'd rather not resort to manual calculations and transform the ActiveSupport::TimeWithZone object from UTC +530 into UTC -400. Is it possible to just change the zone part of a TimeWithZone object without converting it?

P.S. I did come across this question. But it isn't have the answer I'm looking for.(one of the comments even mention it)

It is recommended that all datetime objects should always be stored in UTC -0000, as said here. If yet you want to convert it to do some calculations, use the utc_offset method or convert both objects to UTC by using the utc method, as seen here.
