DateTimeOffset.UtcNow Property

Gets a DateTimeOffset object whose date and time are set to the current Coordinated Universal Time (UTC) date and time and whose offset is TimeSpan.Zero.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static DateTimeOffset UtcNow { get; }

Property Value

Type: System.DateTimeOffset
A DateTimeOffset value whose date and time is the current Coordinated Universal Time (UTC) and whose offset is TimeSpan.Zero.

The UtcNow property computes the current Universal Coordinated Time (UTC) based on the local system's clock time and an offset defined by the local system's time zone.

The precision of the current UTC time's millisecond component depends on the resolution of the system clock. On Windows NT 3.5 and later, and Windows Vista operating systems, the clock's resolution is approximately 10-15 milliseconds.

The following example illustrates the relationship between Coordinated Universal Time (UTC) and local time.

DateTimeOffset localTime = DateTimeOffset.Now;
DateTimeOffset utcTime = DateTimeOffset.UtcNow;

Console.WriteLine("Local Time:          {0}", localTime.ToString("T"));
Console.WriteLine("Difference from UTC: {0}", localTime.Offset.ToString());
Console.WriteLine("UTC:                 {0}", utcTime.ToString("T"));
// If run on a particular date at 1:19 PM, the example produces 
// the following output: 
//    Local Time:          1:19:43 PM 
//    Difference from UTC: -07:00:00 
//    UTC:                 8:19:43 PM
