Exemplos

O exemplo a seguir chama ToUniversalTime o método para converter uma hora local e várias outras vezes em UTC (tempo Universal Coordenado).The following example calls the ToUniversalTime method to convert a local time and several other times to Coordinated Universal Time (UTC).

DateTimeOffset localTime, otherTime, universalTime;
 
// Define local time in local time zone
localTime = new DateTimeOffset(new DateTime(2007, 6, 15, 12, 0, 0));
Console.WriteLine("Local time: {0}", localTime);
Console.WriteLine();

// Convert local time to offset 0 and assign to otherTime
otherTime = localTime.ToOffset(TimeSpan.Zero);
Console.WriteLine("Other time: {0}", otherTime);
Console.WriteLine("{0} = {1}: {2}", 
                  localTime, otherTime, 
                  localTime.Equals(otherTime));
Console.WriteLine("{0} exactly equals {1}: {2}", 
                  localTime, otherTime, 
                  localTime.EqualsExact(otherTime));
Console.WriteLine();
                  
// Convert other time to UTC
universalTime = localTime.ToUniversalTime(); 
Console.WriteLine("Universal time: {0}", universalTime);
Console.WriteLine("{0} = {1}: {2}", 
                  otherTime, universalTime, 
                  universalTime.Equals(otherTime));
Console.WriteLine("{0} exactly equals {1}: {2}", 
                  otherTime, universalTime, 
                  universalTime.EqualsExact(otherTime));
Console.WriteLine();
// The example produces the following output to the console:
//    Local time: 6/15/2007 12:00:00 PM -07:00
//    
//    Other time: 6/15/2007 7:00:00 PM +00:00
//    6/15/2007 12:00:00 PM -07:00 = 6/15/2007 7:00:00 PM +00:00: True
//    6/15/2007 12:00:00 PM -07:00 exactly equals 6/15/2007 7:00:00 PM +00:00: False
//    
//    Universal time: 6/15/2007 7:00:00 PM +00:00
//    6/15/2007 7:00:00 PM +00:00 = 6/15/2007 7:00:00 PM +00:00: True
//    6/15/2007 7:00:00 PM +00:00 exactly equals 6/15/2007 7:00:00 PM +00:00: True

Comentários

Esse método retorna um DateTimeOffset objeto cuja Offset Propriedade está definida como zero.This method returns a DateTimeOffset object whose Offset property is set to zero.

O valor do objeto atual DateTimeOffset e o valor DateTimeOffset do objeto retornado pela chamada do método representam o mesmo ponto no tempo.Both the value of the current DateTimeOffset object and the value of the DateTimeOffset object returned by the method call represent the same point in time. Ou seja, se ambos forem passados para o DateTimeOffset.Equals(DateTimeOffset, DateTimeOffset) método, o método retornará. trueThat is, if both are passed to the DateTimeOffset.Equals(DateTimeOffset, DateTimeOffset) method, the method will return true.
