# To parse the date the input text should include the zimezone so when the
# browser parses the string it will be converted to the local time.
#
# In ruby we can use the following:
#    date.strftime('%Y-%m-%dT%H:%M:%S%z')
#

(($) ->
  $.fn.localtime = ->
    # Makes a string with only two characters, adding a leading zero
    fmtZero = (str) ->
      ('0' + str).slice(-2)

    # This is the function to change if you want to customize the format of the date
    fmtDate= (d) ->
      # format the date
      hour = d.getHours()
      if hour < 12
