See Also: #858
I tried to fix broken padrino-helpers dependenies, and here is the solution for it.
All tests succeed at ruby 1.9.3-p194 and 1.8.7-p358 version.

Incidentally, gems version which I used is following .

I'm running into some ActiveSupport::Time troubles and stumbled upon this.

For me (running on padrino head bc930da) the ActiveSupport Time extensions (like 1.day and friends) don't work.
I figured, that require 'active_support/all' fixes this by requiring active_support/time and active_support/core_ext.

active_support/time will autoload :TimeWithZone, 'active_support/time_with_zone'

Is this valid for the above pull request? Should padrino require active_support/all instead or in addition (due to some reloader autoload problems)?

Best,
Robert
