How MongoDB (Ruby driver) handle Date/DateTime/Time

gistfile1.txt

>> coll.insert({:date => Date.today})
BSON::InvalidDocument: Date is not currently supported; use a UTC Time instance instead.

>> coll.insert({:date => DateTime.now})
BSON::InvalidDocument: DateTime is not currently supported; use a UTC Time instance instead.

>> coll.insert({:date => Time.now}) #=> BSON::ObjectId('4dd39768b98f703261000003')

Just more ideas to handle this, taking last post as reference, thanks

def parse_dates(obj)
    obj.each do |key,value|
        if key =~ /date/
            date = obj[key].split('/') 
            date = "#{date[2]}-#{date[0]}-#{date[1]}T00:00:00+00:00"
            obj[key] = DateTime.strptime(date, '%Y-%m-%dT%H:%M:%S%z').to_time.utc   
        end 
    end
end

a function to parse all elements into hash with word "date" in it key, ex: startdate, enddate, created_at_date, etc. Element with format mm/dd/yyyy
