Unixtime problem

[KfirShtober]

Hello.

I have a task to develop a calendar in C#, therefore - I need to use unixtime I think.

But I don't know how to, can some one explain to me how to convert the date of today to unix time? And how can I add a day to the unixtime of today for example.

Thx guys.

I found the unix portion of the code at the following link.

http://www.codeproject.com/csharp/timestamp.asp

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
            DateTime cDate = DateTime.Now;
            label1.Text = "Current Date and Time: " + cDate;
            label2.Text = "Current Unix Time: " + getUnixTimeStamp(cDate);
            DateTime tmpDate = cDate.AddDays(1);
            label3.Text = "Current Unix Time plus 1 day: " + getUnixTimeStamp(tmpDate);
        }
 
        public static long getUnixTimeStamp(System.DateTime date_time_convert)
        {
            DateTime date_time_base = new DateTime(1970, 1, 1, 0, 0, 0, 0);
 
            TimeSpan span = date_time_convert.ToUniversalTime() - date_time_base;
 
            return (long)span.TotalSeconds;
        }
    }
