     I am using two DateTime Picker (set to BOTH Date&Time) and when I am trying to retrieve data from database, it is throwing an exception. From event viewer, I got this :
    Stack trace:    at System.DateTime.DateToTicks(Int32 year, Int32 month, Int32 day)
       at System.DateTime..ctor(Int32 year, Int32 month, Int32 day)
       at Telerik.Web.UI.Calendar.Utils.Utility.ConvertToServerDateTimeCollection(DateTimeCollection dateTimeCollection, String inputString) in c:\Users\Administrator\Desktop\UI for ASP.NET AJAX\Telerik.Web.UI_2013_2_717_Source\RadControlsAjaxSource\Telerik.Web.UI\Calendar\Utility\Utility.cs:line 274
       at Telerik.Web.UI.RadCalendar.LoadPostData(String postDataKey, NameValueCollection postCollection) in c:\Users\Administrator\Desktop\UI for ASP.NET AJAX\Telerik.Web.UI_2013_2_717_Source\RadControlsAjaxSource\Telerik.Web.UI\Calendar\RadCalendar.cs:line 5041
       at Telerik.Web.UI.RadWebControl.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection) in c:\Users\Administrator\Desktop\UI for ASP.NET AJAX\Telerik.Web.UI_2013_2_717_Source\RadControlsAjaxSource\Telerik.Web.UI\Common\RadWebControl.cs:line 742
       at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad)
       at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)


    •  We are UI for ASP.Net AJAX (Telerik version 2013.2.717.35).
    • It is working fine for few TimeZone like Pacific Time but giving error in like UTC +5.30 etc.
    • The error is only occurring when we are setting it to both (Date & Time ) while it is working fine in only Date Format.


    I tried Debugging into Telerik Source, and I found that the exception is coming in this funtion:

    /// <summary>
    /// Converts an input 2D JavaScript array like [[5,10,2005],[6,10,2005],[7,10,2005]] into a DateTimeCollection.
    /// </summary>
    /// <param name="dateTimeCollection">The DateTimeCollection that will be filled.</param>
    /// <param name="inputString">The input string.</param>
    internal static void ConvertToServerDateTimeCollection(DateTimeCollection dateTimeCollection, string inputString)
    int i, BracketCount = 0;

    if (String.IsNullOrEmpty(inputString)) return;

    for (i = 0; i < inputString.Length; i++)
    if (inputString[i] == '[')
    else if (inputString[i] == ']')
    if (BracketCount != 0)
    throw new FormatException(Constants.Exception.FormatInputJavaScriptDateException);

    // Remove the "[" and the "]"
    inputString = inputString.Replace("[", String.Empty).Replace("]", String.Empty);

    string[] ArrDates = inputString.Split(",".ToCharArray());

    for (i = 0; i < ArrDates.Length / 3; i++)
    DateTime CurrentDateTime = new DateTime(Int32.Parse(ArrDates[i * 3]), Int32.Parse(ArrDates[i * 3 + 1]), Int32.Parse(ArrDates[i * 3 + 2]));
    dateTimeCollection.Add(new RadDate(CurrentDateTime));


    Please suggest some way to get rid from this problem.

    Did you ever resolve this? I have the same issue and seems to be related to the use of time
