Question

I’m developing an application and I need to get the current date from a server (it differs from the machine’s date).
I receive the date from the server and with a simple Split I create a new DateTime:

globalVars.fec = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, int.Parse(infoHour[0]), int.Parse(infoHour[1]), int.Parse(infoHour[2]));

globalVars is a class and fec is a public static variable so that I can access it anywhere in the application (bad coding I know…).
Now I need to have a timer checking if that date is equal to some dates I have stored in a List and if it is equal I just call a function.

List<DateTime> fechas = new List<DateTime>();

Before having to obtain the date from a server I was using computer’s date, so to check if the dates matched I was using this:

private void timerDatesMatch_Tick(object sender, EventArgs e)
{
    DateTime tick = DateTime.Now;
    foreach (DateTime dt in fechas)
    {
        if (dt == tick)
        {
            //blahblah
        }
    }
}

Now I have the date from the server so DateTime.Now can’t be used here. Instead I have created a new timer with Interval=1000 and on tick I’m adding 1 second to globalVars.fec using:

globalVars.fec = globalVars.fec.AddSeconds(1);

But the clock isn’t accurate and every 30 mins the clock loses about 30 seconds.

Is there another way of doing what I’m trying to do? I’ve thought about using threading.timer instead but I need to have access to other threads and non-static functions.

Store the difference between the server’s time and local time. Calculate the servers’ time when you need it using that difference.
