Problem with insert Time to database

Dear all,
I have insert the time to my database but it appear also the date by default.
This is my code in C# :
DateTime date = DateTime.Now;
int hour = date.Hour;
int minute = date.Minute;
int second = date.Second;
string requestedTime = hour+":"+minute+":"+second;
string query = "INSERT INTO workorder([timeRequest]) VALUES("'"+requestTime+"'");
in my database , the column timeRequest appear :1/1/1900 11:59:05 AM
I dont want the date by default to appear, i want only the time like : 11:59:05 AM in my database,
Anyone can help me?
Best Regards,
Moniphal

Use parameterized command to insert data to database. By example:

SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "INSERT INTO workorder(timeRequest) VALUES (@.TimeRequest)";
cmd.CommandType = CommandType.Text
cmd.Parameters.Add(new SqlParameter("@.TimeRequest",myDateTime));
cmd.ExecuteNonQuery();
