title: Regular Expression Date and Time
body: <p>Hi people I have the following express validation </p>
  
  <pre><code>    [Required]
      [RegularExpression("{0:d/M/yyyy HH:mm:ss}" , 
      ErrorMessage = "Wrong Syntax")]
      public string Posted { get; set; }` 
  </code></pre>
  
  <p>But it does not allow the following input which am showing as a example of date and time: 
  12/12/2011 00:00:00 (I do not want these exact numbers the date and time should allow any numbers which is allowed logically by date and time standards)</p>
  
  <p>I get the error message "Wrong Syntax" even when i input the correct code. What seems to be the problem. Any help will be really appreciated Thank You So Much </p>
