Title: Update Utilities.cs

The problem is caused by the thread local culture, i think that the dotnet framework have a bug in the parse method for the datetime.. if the current culture is italian (or another latin language.. i suppose), it simply do not works for the may month.
i wrote this about the topic: http://stackoverflow.com/questions/9521016/datetime-parse-fails-for-today-01-mar-2012-o-0

My fix should work.
