Exemplos

O exemplo a seguir converte UTC (Tempo Universal Coordenado) em Hora Central.

DateTime timeUtc = DateTime.UtcNow;
try
{
   TimeZoneInfo cstZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time");
   DateTime cstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone);
   Console.WriteLine("The date and time are {0} {1}.", 
                     cstTime, 
                     cstZone.IsDaylightSavingTime(cstTime) ?
                             cstZone.DaylightName : cstZone.StandardName);
}
catch (TimeZoneNotFoundException)
{
   Console.WriteLine("The registry does not define the Central Standard Time zone.");
}                           
catch (InvalidTimeZoneException)
{
   Console.WriteLine("Registry data on the Central Standard Time zone has been corrupted.");
}

let timeUtc = DateTime.UtcNow
try
    let cstZone = TimeZoneInfo.FindSystemTimeZoneById "Central Standard Time"
    let cstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone)
    printfn $"The date and time are {cstTime} {if cstZone.IsDaylightSavingTime cstTime then cstZone.DaylightName else cstZone.StandardName}."
with
| :? TimeZoneNotFoundException ->
    printfn "The registry does not define the Central Standard Time zone."
| :? InvalidTimeZoneException ->
    printfn "Registry data on the Central Standard Time zone has been corrupted."

Dim timeUtc As Date = Date.UtcNow
Try
   Dim cstZone As TimeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time")
   Dim cstTime As Date = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone)

                     cstTime, _
                     IIf(cstZone.IsDaylightSavingTime(cstTime), _
                         cstZone.DaylightName, cstZone.StandardName))
Catch e As TimeZoneNotFoundException
   Console.WriteLine("The registry does not define the Central Standard Time zone.")
Catch e As InvalidTimeZoneException
   Console.WriteLine("Registry data on the Central Standard Time zone has been corrupted.")
End Try

Comentários

Ao executar a conversão, o método aplica todas as ConvertTimeFromUtc regras de ajuste em vigor no destinationTimeZone fuso horário.

O comportamento preciso desse método depende do valor da Kind propriedade do dateTime parâmetro , como mostra a tabela a seguir.

Caso a conversão de dateTime resulte em uma data e um valor de hora anterior a DateTime.MinValue ou posterior a DateTime.MaxValue, este método retorna DateTime.MinValue ou DateTime.MaxValue, respectivamente.
