DateTimeOffset.UtcNow Property

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Source:

DateTimeOffset.cs

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

public:
 static property DateTimeOffset UtcNow { DateTimeOffset get(); };

public static DateTimeOffset UtcNow { get; }

static member UtcNow : DateTimeOffset

Public Shared ReadOnly Property UtcNow As DateTimeOffset

Property Value

DateTimeOffset

An object whose date and time is the current Coordinated Universal Time (UTC) and whose offset is Zero.

Examples

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

let localTime = DateTimeOffset.Now
let utcTime = DateTimeOffset.UtcNow

printfn $"Local Time:          {localTime:T}"
printfn $"Difference from UTC: {localTime.Offset}"
printfn $"UTC:                 {utcTime: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

Dim localTime As DateTimeOffset = DateTimeOffset.Now
Dim utcTime As DateTimeOffset = 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

Remarks

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.
