How do you convert epoch time in C#?

Question

How do you convert Unix epoch time into real time in C#? (Epoch beginning 1/1/1970)

Answer 1

// convert datetime to unix epoch seconds
public static long ToUnixTime(DateTime date)
{
    var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
    return Convert.ToInt64((date.ToUniversalTime() - epoch).TotalSeconds);
}

Should use ToUniversalTime() for the DateTime object.
