2. Make warning Regarding Production Servers
3. Point out it can be done from the command line

private void TestDates()
{
DateTime dt = DateTime.Now;
string timeHHMMSS = dt.ToString("HHmmss");

Console.WriteLine(dt);
Console.WriteLine(int.Parse(timeHHMMSS));
Console.WriteLine(timeHHMMSS);
TimeSpan ts = dt.TimeOfDay;
Console.WriteLine(ts.ToString());
timeHHMMSS = dt.ToString("HHmm");
Console.WriteLine(timeHHMMSS);
}

private string TestHHMM()
{
string InputString = DateTime.Now.ToString("HHmm"); // "2200";
if (InputString.Length >= 2)
InputString = InputString.PadLeft(4, '0');
Regex RegexObj = new Regex("^([0-1]\\d|2[0-3])([0-5][0-9])$");
if (RegexObj.IsMatch(InputString))
Console.WriteLine("true");
else
Console.WriteLine("false");
return RegexObj.Replace(InputString, "$1:$2");
}

private string TestDateMonthYear()
{
string InputString = "200819";
Regex RegexObj = new Regex("^(\\d{4})([0]?[1-9]|1[0-2])$");
return RegexObj.Replace(InputString, "$2/$1");
}
