您可以根据所需的时区将日期时间存储到数据库中（无论服务器的时区不同）。



创建一个扩展方法，将服务器的时间转换为所需的时区，然后将其保存到数据库中。

在下面的示例中，我将服务器的时间转换为IST -

You can store the date time into database as per your required timezone (no matter server's timezone is different).

Create an extension method to convert server's time to required timezone and then save it into database.
In following example I am converting server's time to IST -

private static readonly List<timezoneinfo> TimeZoneInfoList = TimeZoneInfo.GetSystemTimeZones().ToList();</timezoneinfo>

public static DateTime ConvertedDateTime(this DateTime dateTime, bool convertToTimeZone = true)
       {
           if (!convertToTimeZone || string.IsNullOrEmpty("Indian Standard Time")) return DateTime.Now.ConvertedDateTime();

           var targetTimeZone = TimeZoneInfoList.SingleOrDefault(x => x.Id.Equals("Indian Standard Time", StringComparison.Ordinal));

           return targetTimeZone != null
               ? TimeZoneInfo.ConvertTime(DateTime.SpecifyKind(dateTime, DateTimeKind.Unspecified), TimeZoneInfo.Local, targetTimeZone)
               : DateTime.Now.ConvertedDateTime();
       }

在数据库中，您将转换日期时间，因此在显示时您只需要选择数据来自数据库并显示它而不进行任何转换。



注意：如果您有多国观众，此解决方案将不适用。

In the database you will have converted datetime, so at the time of display you just need to pick the data from database and display it without any conversion.

Note: This solution will not suitable if you have multi-national audience.
