How to convert Date time from UTC to IST in 12 hours-CodePudding

so i have been trying to convert date time which is saved in DB in utc format. AddedDate: 2022-08-09 12:28:19.717 Now i want to convert it into ist in a format like this: Mon, 09 Aug 2022 05:58 PM

i am using:

Posted on : @( TimeZoneInfo.ConvertTimeFromUtc(Model.AddedDate, TimeZoneInfo.FindSystemTimeZoneById("India Standard Time")))

but it was giving me the same format which is saved in database. (i was rendering the date in view)

CodePudding user response：

Just try to use formatted string. Like this:

Model.AddedDate.ToString("ddd, dd MMM yyyy hh:mm:ss", CultureInfo.InvariantCulture);

CodePudding user response：

Try this You have to convert string to datetime object before you convert it to UTC

        string date = "2022-08-09 12:28:19.717"; 
        DateTime localDateTime = DateTime.Parse(date); 
        DateTime utcDateTime = localDateTime.ToUniversalTime();
        string nzTimeZoneKey = "India Standard Time";
        TimeZoneInfo nzTimeZone = TimeZoneInfo.FindSystemTimeZoneById(nzTimeZoneKey);
        //Console.WriteLine(nzTimeZone);
        DateTime nzDateTime = TimeZoneInfo.ConvertTimeFromUtc(localDateTime, nzTimeZone);
        Console.WriteLine(nzDateTime.ToString("ddd, dd MMM yyyy hh:mm:ss tt", CultureInfo.InvariantCulture));

The one liner

((DateTime)TimeZoneInfo.ConvertTimeFromUtc(DateTime.Parse("2022-08-09 12:28:19.717").ToUniversalTime(), TimeZoneInfo.FindSystemTimeZoneById("India Standard Time"))).ToString("ddd, dd MMM yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);
