Windows PowerShell command on Get-command Set-Date

NAME

Set-Date

SYNOPSIS

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

SYNTAX

Set-Date [-Adjust] [-Confirm] [-DisplayHint {Date | Time | DateTime}] [-WhatIf] []

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

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

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 []

Prompts you for confirmation before running the cmdlet. Required? false Position? named Default value 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. Required? true Position? 0 Default value None

Accept pipeline input? True (ByPropertyName, ByValue)

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.

Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-WhatIf []

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 This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, PipelineVariable, and OutVariable. For more information, see about_CommonParameters (https:/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.
