Set-Date

  • Reference
Module:
Microsoft.PowerShell.Utility

Changes the system time on the computer to a time that you specify.

Syntax

Set-Date
   [-Date] <DateTime>
   [-DisplayHint <DisplayHintType>]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]
Set-Date
   [-Adjust] <TimeSpan>
   [-DisplayHint <DisplayHintType>]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

The Set-Date cmdlet changes the system date and time on the computer to a date and time that you specify.

You can specify a new date and/or time by typing a string or by passing a DateTime or TimeSpan object to Set-Date. To specify a new date or time, use the Date parameter. To specify a change interval, use the Adjust parameter.

Examples

Example 1: Add three days to the system date

This command adds three days to the current system date. It does not affect the time. The command uses the Date parameter to specify the date.

The Get-Date cmdlet returns the current date as a DateTime object. The DateTime object's AddDays method adds a specified number of days (3) to the current DateTime object.

Set-Date -Date (Get-Date).AddDays(3)

Example 2: Set the system clock back 10 minutes

This example sets the current system time back by 10 minutes.

The Adjust parameter allows you to specify an interval of change (minus ten minutes) in the standard time format for the locale.

The DisplayHint parameter tells PowerShell to display only the time, but it does not affect the DateTime object that Set-Date returns.

Set-Date -Adjust -0:10:0 -DisplayHint Time

Example 3: Set the date and time to a variable value

These commands change the system date and time on local computer to the date and time saved in the variable $T. The first command gets the date and stores it in $T.

The second command uses the Date parameter to pass the DateTime object in $T to the Set-Date cmdlet.

$T = Get-Date
Set-Date -Date $T

Example 4: Add 90 minutes to the system clock

These commands advance the system time on the local computer by 90 minutes.

The first command uses the New-TimeSpan cmdlet to create a TimeSpan object with a 90-minute interval, and saves it in the $90mins variable.

The second command uses the Adjust parameter of Set-Date to adjust the date by the value of the TimeSpan object in the $90mins variable.

$90mins = New-TimeSpan -Minutes 90
Set-Date -Adjust $90mins

Parameters

-Adjust

Specifies the value for which this cmdlet adds or subtracts from the current date and time. can type an adjustment in standard date and time format for your locale or use the Adjust parameter to pass a TimeSpan object from New-TimeSpan to Set-Date.

Type:TimeSpan
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Date

Changes the date and time to the specified values. You can type a new date in the short date format and a time in the standard time format for your locale. Or, you can pass a DateTime object from Get-Date.

If you specify a date, but not a time, Set-Date changes the time to midnight on the specified date. If you specify only a time, it does not change the date.

Type:DateTime
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-DisplayHint

Specifies which elements of the date and time are displayed.The acceptable values for this parameter are:

  • Date - displays only the date.
  • Time - displays only the time.
  • DateTime - displays the date and time.

This parameter affects only the display. It does not affect the DateTime object that Get-Date retrieves.

Type:DisplayHintType
Accepted values:Date, Time, DateTime
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

DateTime

You can pipe a date to Set-Date.

Outputs

DateTime

Set-Date returns an object that represents the date that it set.

Notes

  • Use this cmdlet cautiously when changing the date and time on the computer. The change might prevent the computer from receiving system-wide events and updates that are triggered by a date or time. Use the WhatIf and Confirm parameters to avoid errors.
  • You can use standard .NET methods with the DateTime and TimeSpan objects used with Set-Date, such as AddDays, AddMonths, and FromFileTime. For more information, see DateTime Methods and TimeSpan Methods in the .NET SDK.
