Morning All,
I have a variable as follows: $machines = $user2,$name,$serial,$purchased
sample data stored in $machines is:
User1,
Laptop1,
xyz1234,
01/01/2010
I am wanting to create a new variable called $tobereplaced containing all of the records in $machines with a date greater than 4 years old from todays date.
the fuzzy logic code for this im expecting to be someting like $tobereplaced = $machines.$purchased | where {$_$purchased = -getdate > 4 years} etc etc but i cant quite figure it out.
Assistance would be greatly appreciated.
Thanks
$fourYearsAgo = (Get-Date).AddYears(-4)
$tobereplaced = $machines | Where-Object { (Get-Date $_[-1]) -le $fourYearsAgo }
Convert the date as DateTime and compare it against a date four years ago. Like so,
# Assuming $m[3] contains the timestamp, parse it as a DateTime and compare
# against a date four years ago.
if([DateTime]::Parse($m[3]) -le [DateTime]::Now.AddYear(-4)) {
$tobereplaced += $m
}
Depending on your locale, you might need to tell [DateTime]::Parse() how to parse the date. Is 01/12/2010 1st of December, 2010 or 12th January, 2010?

I am getting list of dates and storing it into an array like
$arraylist={2022-03-24T12:05:05Z 2022-03-29T12:04:10Z 2022-03-23T12:54:07Z 2022-03-26T13:15:36Z 2022-03-22T10:06:11Z 2022-03-23T09:54:08Z}
by using a command $arrayList +=$listdate. Now I want the sorted list of date alone like
$sortedlist={2022-03-29 2022-03-26 2022-03-24 2022-03-23 2022-03-23 2022-03-22}
Not with timing. I am doing these things in PowerShell. The details of date which I am getting is in string format not in date-time format. can anyone help me out with this?
I initially split the date with $arrayList.Split('T') and stored the date alone in another array. But it is not sorted form. I tried to sort it but I am not getting desired sorted list.
Is there any other way to get desired sorted list of date?
If you are getting your dates in a single string (as per the example of data you have provided) it would be possible to split the string into an array and then convert the array of strings into datetime objects:
$DateString = "2022-03-24T12:05:05Z 2022-03-29T12:04:10Z 2022-03-23T12:54:07Z 2022-03-26T13:15:36Z 2022-03-22T10:06:11Z 2022-03-23T09:54:08Z"
$array = $DateString -split " "
$FormattedDates = Foreach ($item in $array){
[DateTime]::ParseExact($Item, "yyyy-MM-ddTHH:mm:ssK", $null)
}
$FormattedDates | Sort | ForEach-Object {$_.ToString("yyyy-MM-dd")}
I have an use case where user passes a date from the past. But I need to check if it's a Wednesday. If not, I want to be able to set it to next Wednesday 5 AM. Can somebody please tell me what would be best approach to go about this using PS?
Thanks.
Fortunately [datetime] structs have a DayOfWeek property we can use to check that!
Simply advance the date by 1 day at a time until you reach Wednesday:
function Get-UpcomingWednesdayAt5
{
param(
[datetime]$Date
)
while($Date.DayOfWeek -ne [System.DayOfWeek]::Wednesday){
# advance 1 day at a time until its wednesday
$Date = $Date.AddDays(1)
}
# Create new [datetime] object with same Date but Time set to 5AM
return Get-Date -Date $Date -Hour 5
}
Is it possible to compare 2 custom dates. Am trying check if variables hold date1 is lessthan date2, if so, report saying date1 is older date.
I getting both dates from a. date1 from log file and date2 from application itself
now, both date1 and date2 are in required format ie,
$Date1 = Tue,Aug 16, 2016 12:40:03
$Date2 = Mon,Aug 22, 2016 16:33:02
my next step is compare these 2 dates and report if date1 is older date compare to Date2, which I don't know how to proceed.. Any help/ideas is much appreciated.
Thanks to Pete and Ansgar Wiechers
updated working Code :
$Date1DateTime = [DateTime]::ParseExact($Date1,'ddd,MMM d, yyyy, HH:mm:ss',[Globalization.CultureInfo]::InvariantCulture); $Date2DateTime = [DateTime]::ParseExact($Date2,'ddd,MMM d, yyyy, HH:mm:ss',[Globalization.CultureInfo]::InvariantCulture); $Date1DateTime -lt $Date2DateTime
You can only compare date strings if the string sort order is the same as the date sort order. For instance, date strings in ISO format are comparable:
2016-08-16T12:40:03
2016-08-22T16:33:02
Date strings in your custom format are not, because T comes after M, but August 16 should actually come before August 22:
Tue,Aug 16, 2016 12:40:03
Mon,Aug 22, 2016 16:33:02
If you don't have the date strings in ISO format it's usually better to parse them into actual DateTime values (as #PetSerAl suggested), particularly if your reference value is originally a DateTime anyway.
$fmt = 'ddd,MMM d, yyyy, HH:mm:ss'
$culture = [Globalization.CultureInfo]::InvariantCulture
$Date1 = Get-Date $LogFileDate
$val = (b2b.exe -readparams $param | Select-Object -Skip 1 -First 1) -split '='
$Date2 = [DateTime]::ParseExact($val[1], $fmt, $culture)
if ($Date1 -lt $Date2) {
...
}
I have a script that outputs to CSV all items/files from all Lists and Libraries. In addition, it displays the current and previous versions of an item/file. This also displays which user modified the file for each version and also displays the date/time the file was modified for every version:
function Get-DocInventory([string]$siteUrl) {
$web = Get-SPWeb "http://contoso.com/sites/Depts3/HBG"
foreach ($list in $web.Lists) {
foreach ($item in $list.Items) {
foreach($version in $item.Versions){
$data = #{
"Version" = $version.VersionLabel
"List Name" = $list.Title
"Created By" = $item["Author"]
"Created Date" = ($item["Created"] -as [datetime]).DateTime
"Modified By" = $version["Editor"]
"Modified Date" = ($version["Modified"] -as [datetime]).DateTime
"Item Name" = $item.Name
}
New-Object PSObject -Property $data | Select "List Name", "Item Name", "Version", "Created By", "Created Date", "Modified By", "Modified Date"
}
}
$web.Dispose();
}
}
Get-DocInventory | Export-Csv -NoTypeInformation -Path C:\GenerateReport.csv
Below is a sample of what the script outputs:
And below is an excel example of what I see when I go to the Version History of the Lions.pdf file:
I have 2 problems:
The column Modified By is displaying email and domain username which is not required.
My script displays the column Modified Date as 5 hours ahead. The script output for Version 1 of Lions.pdf displays time as 11:23 AM. But when I go to Version History of Lions.pdf it says that Version 1 was modified at 6:23 AM. The time discrepancy is the same across the board as 5 hours ahead which is incorrect.
I can't seem to figure out what I am doing wrong here. Can someone please assist in the issue I am having? My main concern is the time and I would greatly appreciate any assistance.
User Fields
Normally in server side code, accessing a user field value using array notation (eg myItem["Author"]) would return an object that you would cast to an appropriate type (Microsoft.SharePoint.SPFieldUserValue). Powershell, however, automatically casts these values to strings, which is why you're getting undesirable values.
Fortunately, there's a way around it! First, get the field itself as an object, then pass the field value into the field's GetFieldValue() method.
$userField = $item.Fields.GetField("Author");
$authorObject = $userField.GetFieldValue($item["Author"]);
You'll then have an object with properties you can access to retrieve the desired values, such as LookupValue for the user's display name on the site.
$authorName = $authorObject.LookupValue;
Date Fields
Date fields are little easier, because Powershell will actually hand them over to you as DateTime objects.
To format a DateTime object, you can just call .ToString() and pass in a parameter indicating the desired format.
$data = #{
...
"Modified Date" = $item["Modified"].ToString("MM/dd/yyyy h:mm tt");
...
}
Time Discrepancy
This is most likely attributable to your local timezone. The times displayed on a SharePoint site via the browser are determined by your PC's timezone settings. The times actually saved to SharePoint's underlying database are determined by the server's timezone settings.
To reconcile them, you can use the DateTime object's .ToUniversalTime() method to get a corresponding DateTime object in UTC time (and optionally offset it as desired until it aligns with the local timezone and daylight savings adjustments).
Edit: I'm guessing you're in US Eastern time (UTC-5) and it's giving you results in UTC time (Universal Coordinated Time, which is 5 hours ahead of you except during daylight saving time). You should be able to offset the hours manually to account for this.
$localOffset = -5;
$modified = $version["Modified"] -as [datetime];
if($modified.IsDaylightSavingTime()){$localOffset += 1;}
$modifiedLocal = $modified.addHours(-$localOffset);
Using a Powershell date object how do you get the day number of the week, 0 to 6 where 0 would be Sunday and 6 would be Saturday. I know that I can get the day name with the code below but how do I get the number as there is no DayNumberOfWeek or equivalent property?
(Get-Date).DayOfWeek
I suppose I could use the day name from the code above in a switch statement to convert it to a number but that doesn't seem to be very eloquent.
like this:
( get-date ).DayOfWeek.value__
I suggest for the future to investigate what properties an object in this way:
( get-date ).DayOfWeek | gm -f # gm is an alias for get-member
Well, the DayOfWeek property of a DateTime is not a string but rather a DayOfWeek enum, so the shortest answer is probably
[Int] (Get-Date).DayOfWeek # returns 0 through 6 for current day of week
Or
[Int] [DayOfWeek] "Wednesday" # returns 3
Get-Date -UFormat %u
will return formated date.

On Friday the 17th:
(get-date).DayOfWeek.value__
Returns 5
(Get-Date).DayOfWeek
Returns Friday
(Get-Date).Day
Returns 17
