NAME Set-Date



SYNOPSIS

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





SYNTAX

Set-Date [-Adjust] <TimeSpan> [-Confirm] [-DisplayHint {Date | Time | DateTime}] [-WhatIf] [<CommonParameters>]



Set-Date [-Date] <DateTime> [-Confirm] [-DisplayHint {Date | Time | DateTime}] [-WhatIf] [<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.





PARAMETERS

-Adjust <TimeSpan>

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 .



Required? true

Position? 0

Default value None

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-Confirm [<SwitchParameter>]

Prompts you for confirmation before running the cmdlet.



Required? false

Position? named

Default value False

Accept pipeline input? False

Accept wildcard characters? false



-Date <DateTime>

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.



Required? true

Position? 0

Default value None

Accept pipeline input? True (ByPropertyName, ByValue)

Accept wildcard characters? false



-DisplayHint <DisplayHintType>

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.



Required? false

Position? named

Default value None

Accept pipeline input? False

Accept wildcard characters? false



-WhatIf [<SwitchParameter>]

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



Required? false

Position? named

Default value False

Accept pipeline input? False

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

System.DateTime

You can pipe a date to Set-Date .





OUTPUTS

System.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 Methodshttps://msdn.microsoft.com/en-us/library/system.datetime_methods(v=vs.110).aspx and TimeSpan

Methodshttps://msdn.microsoft.com/en-us/library/system.timespan_methods(v=vs.110).aspx.



Example 1: Add three days to the system date



PS C:\\>Set-Date -Date (Get-Date).AddDays(3)



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. It

uses the Get-Date cmdlet to get the current date and time and applies the AddDays .NET method for DateTime objects with a value of 3 (days).

Example 2: Set the system clock back 10 minutes



PS C:\\>Set-Date -Adjust -0:10:0 -DisplayHint Time



This command sets the current system time back by 10 minutes. It uses the Adjust parameter to specify an interval of change and the time change

(minus ten minutes) in standard time format for the locale. The DisplayHint parameter tells Windows PowerShell to display only the time, but it

does not affect the DateTime object that Set-Date returns.

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



PS C:\\>$T = Get-Date

PS C:\\>Set-Date -Date $T



These commands change the system date and time on the 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.

Example 4: Add 90 minutes to the system clock



PS C:\\>$90mins = New-TimeSpan -Minutes 90

PS C:\\>Set-Date -Adjust $90mins



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 then it saves the TimeSpan object 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.
