DateTimeOffset(DateTime)

Source:: DateTimeOffset.cs

Source:: DateTimeOffset.cs

Source:: DateTimeOffset.cs

Initializes a new instance of the DateTimeOffset structure using the specified DateTime value.

public:
 DateTimeOffset(DateTime dateTime);

public DateTimeOffset (DateTime dateTime);

new DateTimeOffset : DateTime -> DateTimeOffset

Public Sub New (dateTime As DateTime)

Parameters

dateTime: DateTime

A date and time.

Exceptions

ArgumentOutOfRangeException

The Coordinated Universal Time (UTC) date and time that results from applying the offset is earlier than DateTimeOffset.MinValue.

-or-

The UTC date and time that results from applying the offset is later than DateTimeOffset.MaxValue.

Examples

The following example illustrates how the value of the DateTime.Kind property of the dateTime parameter affects the date and time value that is returned by this constructor.

DateTime localNow = DateTime.Now;
DateTimeOffset localOffset = new DateTimeOffset(localNow);
Console.WriteLine(localOffset.ToString());

DateTime utcNow = DateTime.UtcNow;
DateTimeOffset utcOffset = new DateTimeOffset(utcNow);
Console.WriteLine(utcOffset.ToString());

DateTime unspecifiedNow = DateTime.SpecifyKind(DateTime.Now,
                               DateTimeKind.Unspecified);
DateTimeOffset unspecifiedOffset = new DateTimeOffset(unspecifiedNow);
Console.WriteLine(unspecifiedOffset.ToString());
//
// The code produces the following output if run on Feb. 23, 2007, on
// a system 8 hours earlier than UTC:
//   2/23/2007 4:21:58 PM -08:00
//   2/24/2007 12:21:58 AM +00:00
//   2/23/2007 4:21:58 PM -08:00

let localNow = DateTime.Now
let localOffset = DateTimeOffset localNow
printfn $"{localOffset}"

let utcNow = DateTime.UtcNow
let utcOffset = DateTimeOffset utcNow
printfn "{utcOffset}"

let unspecifiedNow = DateTime.SpecifyKind(DateTime.Now, DateTimeKind.Unspecified)
let unspecifiedOffset = DateTimeOffset unspecifiedNow
printfn $"{unspecifiedOffset}"

// The code produces the following output if run on Feb. 23, 2007, on
// a system 8 hours earlier than UTC:
//   2/23/2007 4:21:58 PM -08:00
//   2/24/2007 12:21:58 AM +00:00
//   2/23/2007 4:21:58 PM -08:00

Dim localNow As Date = Date.Now
Dim localOffset As New DateTimeOffset(localNow)
Console.WriteLine(localOffset.ToString())

Dim utcNow As Date = Date.UtcNow
Dim utcOffset As New DateTimeOffset(utcNow)
Console.WriteLine(utcOffset.ToString())

Dim unspecifiedNow As Date = Date.SpecifyKind(Date.Now, _
                                  DateTimeKind.Unspecified)
Dim unspecifiedOffset As New DateTimeOffset(unspecifiedNow)
Console.WriteLine(unspecifiedOffset.ToString())
'
' The code produces the following output if run on Feb. 23, 2007, on
' a system 8 hours earlier than UTC:
'    2/23/2007 4:21:58 PM -08:00
'    2/24/2007 12:21:58 AM +00:00
'    2/23/2007 4:21:58 PM -08:00

Remarks

This constructor's behavior depends on the value of the DateTime.Kind property of the dateTime parameter:

If the value of DateTime.Kind is DateTimeKind.Utc, the DateTime property of the new instance is set equal to dateTime, and the Offset property is set equal to Zero.
If the value of DateTime.Kind is DateTimeKind.Local or DateTimeKind.Unspecified, the DateTime property of the new instance is set equal to dateTime, and the Offset property is set equal to the offset of the local system's current time zone.

Applies to

DateTimeOffset(DateTime, TimeSpan)

Source:: DateTimeOffset.cs

Source:: DateTimeOffset.cs

Source:: DateTimeOffset.cs

Initializes a new instance of the DateTimeOffset structure using the specified DateTime value and offset.

public:
 DateTimeOffset(DateTime dateTime, TimeSpan offset);

public DateTimeOffset (DateTime dateTime, TimeSpan offset);

new DateTimeOffset : DateTime * TimeSpan -> DateTimeOffset

Public Sub New (dateTime As DateTime, offset As TimeSpan)

Parameters

dateTime: DateTime

A date and time.

offset: TimeSpan

The time's offset from Coordinated Universal Time (UTC).

Exceptions

ArgumentException

dateTime.Kind equals Utc and offset does not equal zero.

-or-

dateTime.Kind equals Local and offset does not equal the offset of the system's local time zone.

-or-

offset is not specified in whole minutes.

ArgumentOutOfRangeException

offset is less than -14 hours or greater than 14 hours.

-or-

UtcDateTime is less than DateTimeOffset.MinValue or greater than DateTimeOffset.MaxValue.

Examples

The following example shows how to initialize a DateTimeOffset object with a date and time and the offset of the local time zone when that time zone is not known in advance.

DateTime localTime = new DateTime(2007, 07, 12, 06, 32, 00);
DateTimeOffset dateAndOffset = new DateTimeOffset(localTime,
                         TimeZoneInfo.Local.GetUtcOffset(localTime));
Console.WriteLine(dateAndOffset);
// The code produces the following output:
//    7/12/2007 6:32:00 AM -07:00

let localTime = DateTime(2007, 07, 12, 06, 32, 00)
let dateAndOffset = DateTimeOffset(localTime, TimeZoneInfo.Local.GetUtcOffset localTime)
printfn $"{dateAndOffset}"
// The code produces the following output:
//    7/12/2007 6:32:00 AM -07:00

Dim localTime As Date = #07/12/2007 6:32AM#
Dim dateAndOffset As New DateTimeOffset(localTime, _
                         TimeZoneInfo.Local.GetUtcOffset(localTime))
Console.WriteLine(dateAndOffset)
' The code produces the following output:
'    7/12/2007 6:32:00 AM -07:00

Remarks

This constructor's behavior depends in part on the value of the Kind property of the dateTime parameter:

If the value of Kind is DateTimeKind.Utc, the value of the offset parameter must be 0 or an ArgumentException is thrown.
If the value of Kind is DateTimeKind.Local, the value of the offset parameter must be equal to the local time zone's offset from Coordinated Universal Time (UTC) for that particular date or an ArgumentException is thrown.
If the value of Kind is DateTimeKind.Unspecified, the offset parameter can have any valid value.

Applies to

DateTimeOffset(Int64, TimeSpan)

Source:: DateTimeOffset.cs

Source:: DateTimeOffset.cs

Source:: DateTimeOffset.cs

Initializes a new instance of the DateTimeOffset structure using the specified number of ticks and offset.

public:
 DateTimeOffset(long ticks, TimeSpan offset);

public DateTimeOffset (long ticks, TimeSpan offset);

new DateTimeOffset : int64 * TimeSpan -> DateTimeOffset

Public Sub New (ticks As Long, offset As TimeSpan)

Parameters

ticks: Int64

A date and time expressed as the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight on January 1, 0001.

offset: TimeSpan

The time's offset from Coordinated Universal Time (UTC).

Exceptions

ArgumentException

offset is not specified in whole minutes.

ArgumentOutOfRangeException

The UtcDateTime property is earlier than DateTimeOffset.MinValue or later than DateTimeOffset.MaxValue.

-or-

ticks is less than DateTimeOffset.MinValue.Ticks or greater than DateTimeOffset.MaxValue.Ticks.

-or-

offset is less than -14 hours or greater than 14 hours.

Examples

The following example initializes a DateTimeOffset object by using the number of ticks in an arbitrary date (in this case, July 16, 2007, at 1:32 PM) with an offset of -5.

DateTime dateWithoutOffset = new DateTime(2007, 7, 16, 13, 32, 00);
DateTimeOffset timeFromTicks = new DateTimeOffset(dateWithoutOffset.Ticks,
                               new TimeSpan(-5, 0, 0));
Console.WriteLine(timeFromTicks.ToString());
// The code produces the following output:
//    7/16/2007 1:32:00 PM -05:00

let dateWithoutOffset = DateTime(2007, 7, 16, 13, 32, 00)
let timeFromTicks = DateTimeOffset(dateWithoutOffset.Ticks, TimeSpan(-5, 0, 0))
printfn $"{timeFromTicks}"
// The code produces the following output:
//    7/16/2007 1:32:00 PM -05:00

Dim dateWithoutOffset As Date = #07/16/2007 1:32PM#
Dim timeFromTicks As New DateTimeOffset(datewithoutOffset.Ticks, _
                         New TimeSpan(-5, 0, 0))
Console.WriteLine(timeFromTicks.ToString())
' The code produces the following output:
'    7/16/2007 1:32:00 PM -05:00

Remarks

Ordinarily, trying to call the DateTimeOffset constructor to instantiate a DateTimeOffset value with a local time and an offset other than that of the local time zone throws an ArgumentException. You can use this overload of the DateTimeOffset constructor to work around this limitation. The following example uses the local time's number of ticks to instantiate a DateTimeOffset value whose offset does not necessarily represent that of the local time:

DateTime localTime = DateTime.Now;
DateTimeOffset nonLocalDateWithOffset = new DateTimeOffset(localTime.Ticks,
                                  new TimeSpan(2, 0, 0));
Console.WriteLine(nonLocalDateWithOffset);
//
// The code produces the following output if run on Feb. 23, 2007:
//    2/23/2007 4:37:50 PM +02:00

let localTime = DateTime.Now
let nonLocalDateWithOffset = DateTimeOffset(localTime.Ticks, TimeSpan(2, 0, 0))
printfn $"{nonLocalDateWithOffset}"
// The code produces the following output if run on Feb. 23, 2007:
//    2/23/2007 4:37:50 PM +02:00

Dim localTime As Date = Date.Now
Dim nonLocalDateWithOffset As New DateTimeOffset(localTime.Ticks, _
                                  New TimeSpan(2, 0, 0))
Console.WriteLine(nonLocalDateWithOffset)

Examples

The following example uses instances of both the HebrewCalendar class and the HijriCalendar class to instantiate a DateTimeOffset value. That date is then displayed to the console using the respective calendars and the Gregorian calendar.

CultureInfo fmt;
int year;
Calendar cal;
DateTimeOffset dateInCal;

// Instantiate DateTimeOffset with Hebrew calendar
year = 5770;
cal = new HebrewCalendar();
fmt = new CultureInfo("he-IL");
fmt.DateTimeFormat.Calendar = cal;
dateInCal = new DateTimeOffset(year, 7, 12,
                               15, 30, 0, 0,

                               new TimeSpan(2, 0, 0));
// Display the date in the Hebrew calendar
Console.WriteLine("Date in Hebrew Calendar: {0:g}",
                   dateInCal.ToString(fmt));

Remarks

The year, month, day, hour, minute, second, and millisecond parameters all reflect values expressed in the calendar specified by the calendar parameter. An exception is thrown if these values form a date and time that cannot be expressed by using this calendar.

Important

Eras in the Japanese calendars are based on the emperor's reign and are therefore expected to change. For example, May 1, 2019 marked the beginning of the Reiwa era in the JapaneseCalendar and JapaneseLunisolarCalendar. Such a change of era affects all applications that use these calendars. For more information and to determine whether your applications are affected, see Handling a new era in the Japanese calendar in .NET. For information on testing your applications on Windows systems to ensure their readiness for the era change, see Prepare your application for the Japanese era change. For features in .NET that support calendars with multiple eras and for best practices when working with calendars that support multiple eras, see Working with eras.
