Software – PHP WEB CSS HTML C# AJAX QCODO SEO JAVA SCRIPT

I used *nix timestamp in my WEB project with MySQL database. To have a access via C# desktop program on timestamp datafield and vice versa i use this functions:

static DateTime ConvertFromUnixTimestamp(double timestamp)
{
DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
return origin.AddSeconds(timestamp);
}

static double ConvertToUnixTimestamp(DateTime date)
{
DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
TimeSpan diff = date - origin;
return Math.Floor(diff.TotalSeconds);
}
