New-TimeSpan

  • Reference
Module:
Microsoft.PowerShell.Utility

Creates a TimeSpan object.

Syntax

New-TimeSpan
   [[-Start] <DateTime>]
   [[-End] <DateTime>]
   [<CommonParameters>]
New-TimeSpan
   [-Days <Int32>]
   [-Hours <Int32>]
   [-Minutes <Int32>]
   [-Seconds <Int32>]
   [-Milliseconds <Int32>]
   [<CommonParameters>]

Description

The New-TimeSpan cmdlet creates a TimeSpan object that represents a time interval. You can use a TimeSpan object to add or subtract time from DateTime objects.

Without parameters, a New-TimeSpan command returns a TimeSpan object that represents a time interval of zero.

Examples

Example 1: Create a TimeSpan object for a specified duration

This command creates a TimeSpan object with a duration of 1 hour and 25 minutes and stores it in a variable named $TimeSpan. It displays a representation of the TimeSpan object.

$TimeSpan = New-TimeSpan -Hours 1 -Minutes 25
$TimeSpan

Days              : 0
Hours             : 1
Minutes           : 25
Seconds           : 0
Milliseconds      : 0
Ticks             : 51000000000
TotalDays         : 0.0590277777777778
TotalHours        : 1.41666666666667
TotalMinutes      : 85
TotalSeconds      : 5100
TotalMilliseconds : 5100000

Example 2: Create a TimeSpan object for a time interval

This example creates a new TimeSpan object that represents the interval between the time that the command is run and January 1, 2010.

This command doesn't require the Start parameter, because the default value of the Start parameter is the current date and time.

New-TimeSpan -End (Get-Date -Year 2010 -Month 1 -Day 1)

Example 3: Get the date 90 days from the current date

$90days = New-TimeSpan -Days 90
(Get-Date) + $90days

These commands return the date that is 90 days after the current date.

Example 4: Discover the TimeSpan since a file was updated

This command tells you how long it has been since the about_remote help file was last updated. You can use this command format on any file, or any other object that has a LastWriteTime property.

This command works because the Start parameter of New-TimeSpan has an alias of LastWriteTime. When you pipe an object that has a LastWriteTime property to New-TimeSpan, PowerShell uses the value of the LastWriteTime property as the value of the Start parameter.

Parameters

-Days

Specifies the days in the time span. The default value is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-End

Specifies the end of a time span. The default value is the current date and time.

Type:DateTime
Position:1
Default value:Current date and time
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-Hours

Specifies the hours in the time span. The default value is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Milliseconds

Specifies the length of the time span in milliseconds. The default value is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Minutes

Specifies the minutes in the time span. The default value is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Seconds

Specifies the length of the time span in seconds. The default value is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Start

Specifies the start of a time span. Enter a string that represents the date and time, such as "3/15/09" or a DateTime object, such as one from a Get-Date command. The default value is the current date and time.

You can use Start or its alias, LastWriteTime. The LastWriteTime alias lets you pipe objects that have a LastWriteTime property, such as files in the file system [System.Io.FileIO], to the Start parameter of New-TimeSpan.

Type:DateTime
Aliases:LastWriteTime
Position:0
Default value:Current date and time
Required:False
Accept pipeline input:True
Accept wildcard characters:False

Inputs

DateTime

You can pipe a DateTime object representing the start time to this cmdlet.

Outputs

TimeSpan

This cmdlet returns an object representing the time span.
