title: Converting string to time
body: <p>I have string like this:"0:385" (first number is seconds, next numbers are milliseconds), I want to use in datagridview with sorting like numbers (not like strings) so I am trying to make DateTime from string but I am not sure how exactly do this. I know I should use method Parse (or ParseExact) but when I tried it it says "String was not recognized as a valid DateTime.". I read some articles about that but I am not sure how exactly use IFormatProvider and next arguments.
  Thanks for help</p>
