Question

I have a date in XML:

<time>1340517600</time>

How can I convert it to a DateTime in C#?

Answer 1

That’s a Unix timestamp for “Sun, 24 Jun 2012 06:00:00 GMT”.

To convert from a Unix timestamp to a .NET DateTime, look at these questions:

• How to convert a Unix timestamp to DateTime and vice versa?
• Parsing unix time in C#

Here is Jon Skeet’s solution:

private static readonly DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, 
                                                      DateTimeKind.Utc);

public static DateTime UnixTimeToDateTime(string text)
{
    double seconds = double.Parse(text, CultureInfo.InvariantCulture);
    return Epoch.AddSeconds(seconds);
}
