SYNOPSIS

Creates a TimeSpan object.

SYNTAX

Date (Default)

New-TimeSpan [[-Start] <DateTime>] [[-End] <DateTime>] [<CommonParameters>]

Time

New-TimeSpan [-Days <Int32>] [-Hours <Int32>] [-Minutes <Int32>] [-Seconds <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 --------------------------

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.

-------------------------- EXAMPLE 2 --------------------------

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.

-------------------------- EXAMPLE 3 --------------------------

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.

-------------------------- EXAMPLE 4 --------------------------

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

# 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.

PARAMETERS

-Days

Indicates the days in the time span. The default is 0.

Type: Int32
Parameter Sets: Time
Aliases: 

Required: False
Position: Named
Default value: 0
Accept pipeline input: False
Accept wildcard characters: False

-End

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

Type: DateTime
Parameter Sets: Date
Aliases: 

Required: False
Position: 2
Default value: Current date and time
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Hours

Indicates the hours in the time span. The default is zero.

Type: Int32
Parameter Sets: Time
Aliases: 

Required: False
Position: Named
Default value: 0
Accept pipeline input: False
Accept wildcard characters: False

-Minutes

Indicates the minutes in the time span. The default is 0.

Type: Int32
Parameter Sets: Time
Aliases: 

Required: False
Position: Named
Default value: 0

Required: False
Position: 1
Default value: Current date and time
Accept pipeline input: True (ByPropertyName, ByValue)
