At some point in the past week, my production logs began showing bizarre numbers that don't ad up, like: Completed in 52ms (View: 26, DB: 1129) This query did take over one second.

I have some code that simply accesses a datetime field so activerecord converts it to a Time object automatically when I read it: @some_appointment.some_time The problem is that sometimes the "some_time" datetime column has bad data. "0209-12-20" instead of "2009-12-20". This causes to Ruby to throw a "year too big to marshal" error...
I've been looking at the new options available in HTML5 forms, such as declaring input types as "email", "url", and "number", as described here.
