Ajax time doesn't work

Hello Everyone,

I used sql server 2005, VS 2008, asp, vb.net andajax in my web form for date and time.  The date is working fine, but the time is not.  When I tried to save the data into the data tables, I encountered this "sqlTypeException was unhandled by user code" - sqlDateTime overflow.  Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM

Would someone please help me take a look at what I have below and give me some advice.  All of your help is greatly appreciated!  Thank you very much in advance!

I have 4 textboxes:
txtDateOccured 
txtTimeOccured
txtDateReported
txtTimeReported

I used sql server 2005 and I defined the data type as follows:  I also tried datetime datatype for TimeOccured and Time reported, but It did not work.
DateOccured - datetime
TimeOccured - nvarchar(11)
DateReported - datetime
TimeReported - nvarchar(11)

This is what I entered:
Date Occured: 05/16/2013  
Time Occured: 10:30:00 AM
Date Reported: 05/17/2013
Time Reported: 12:30:00 PM
