Convert server UTC time to client local time

Question

I get from server native (C++) application a FILETIME structure in UTC format. On the managed (C#) client side I need to show it as client(!) local time. Do I need along with FILETIME transfer information about server time zone to accomplish this? Or such information already contains in FILETIME in UTC format?

It is not "server UTC time", it is "UTC time". TC is absolute and not machine depenadnt (unless the clock on the machine is simply set wrong). — TomTom, Dec 23 '11 at 09:41

You can convert a UTC DateTime to local Time using TimeZoneInfo

Sample

TimeZoneInfo.ConvertTimeFromUtc(YourDateTime, TimeZoneInfo.Local);

You can convert a UTC DateTime to any timezone, if you know the name. For example.

TimeZoneInfo.ConvertTimeFromUtc(YourDateTime, 
                TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time"));

But how do I found out the client TimeZone? TimeZoneInfo.Local returns the SERVER's. – Joao Leme Jan 25 '13 at 12:40
Do you mean in a ASP.NET Application ? – dknaack Jan 25 '13 at 13:53
Yes, I was regarding a webapp but I guess its not the case here. – Joao Leme Jan 28 '13 at 16:39

I don't know what your structure is, but if you can convert it to standard time string, DateTime class will parse it. Then simply use the ToLocalTime method.

DateTime time = DateTime.Parse(FILETIME.ToString());
time.ToLocalTime();

create a class
public class TimeConverter
    {
        public static DateTime ConvertToLocalTime(DateTime utcTime, string timeZoneId)
        {
            if (string.IsNullOrEmpty(timeZoneId))
            {
                return utcTime;
            }
            return TimeZoneInfo.ConvertTimeBySystemTimeZoneId(utcTime, timeZoneId);
        }
}

In controller use TimeConverter

TimeConverter.ConvertToLocalTime(Date, yourTimeZone));

Convert server UTC time to client local time
