New-TimeSpan [-Days <Int32>] [-Hours <Int32>] [-Minutes <Int32>] [-Seconds <Int32>] [<CommonParameters>]
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.
Specifies the days in the time span. The default value is 0.
Specifies the end of a time span. The default value is the current date and time.
Specifies the hours in the time span. The default value is zero.
Specifies the minutes in the time span. The default value is 0.
Specifies the length of the time span in seconds. The default value is 0.
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 .
This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.
PS C:\> $TimeSpan = New-TimeSpan -Hour 1 -Minute 25
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.
PS C:\> new-timespan -end (get-date -year 2010 -month 1 -day 1)
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 does not require the Start parameter, because the default value of the Start parameter is the current date and time.
PS C:\> $90days = New-TimeSpan -Days 90 PS C:\> (Get-Date) + $90days
These commands return the date that is 90 days after the current date.
PS C:\> dir $pshome\en-us\about_remote.help.txt | New-TimeSpan Days : 321 Hours : 21 Minutes : 59 Seconds : 22 Milliseconds : 312 Ticks : 278135623127728 TotalDays : 321.916230471907 TotalHours : 7725.98953132578 TotalMinutes : 463559.371879547 TotalSeconds : 27813562.3127728 TotalMilliseconds : 27813562312.7728 PS C:\> # Equivalent to: PS C:\> New-TimeSpan -Start (dir $pshome\en-us\about_remote.help.txt).lastwritetime
This command tells you how long it has been since the about_remote.help.txt file was last updated. You can use this command format on any file, and on 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 , Windows PowerShell uses the value of the LastWriteTime property as the value of the Start parameter.
