public static string ConvertStringToHex(string asciiString)
{
    string hex = "";
    foreach (char c in asciiString)
    {
        int tmp = c;
        hex += String.Format("{0:x2}", (uint)System.Convert.ToUInt32(tmp.ToString()));
    }
    return hex;
}

You can do following with C#.

DateTime dt = new DateTime();
dt = DateTime.Now;
//Convert date time format 20170710041800
string str = dt.ToString("yyyyMMddhhmmss");           
//Convert to Long 
long decValue = Convert.ToInt64(str);
//Convert to HEX 1245D8F5F7C8
string hexValue = decValue.ToString("X");
//Hex To Long again 20170710041800
long decAgain = Int64.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

Please mark as answer if it is helpfull to you

You can do: 

string hexValue = DateTime.Now.Ticks.ToString("X2");

This will give you the hex value.

To convert it back to DateTime you do: 

DateTime dateTime = new DateTime(Convert.ToInt64(hexValue, 16));
