Add-History date behaviour changed from 7.1 to 7.2 - now requires least significant centred format. #15949
Description
Prerequisites
- Write a descriptive title.
- Make sure you are able to repro it on the latest released version
- Search the existing issues.
- Refer to the FAQ.
- Refer to Differences between Windows PowerShell 5.1 and PowerShell.
Steps to reproduce
On a machine where the date format is not US
- Export history to a csv file with
Get-History | Export-Csv -path $logfile -encoding unicode -NoTypeInformation - Import the last item of the history with
$histitem = Import-Csv -Path $logfile | Select-Object -last 1 - Load the item into the the history with
$histitem | Add-History - Change to US date format, with
$histitem.EndExecutionTime = "08/18/2021 16:43:50"; $histitem.StartExecutionTime = "08/18/2021 16:43:50"- note that the imported fields are strings, not[datetime]objects. - Import the modified item with
$histitem | Add-History
Expected behavior
On a non-US machine the import at step 3 works , and the import at step 5 generates the message
"Add-History: Cannot add history because the input object has a format that is not valid."Actual behavior
On Windows PowerShell, PowerShell Core 6.x and Powershell 7 and 7.1 the local date format succeeds and US date format fails.
On PowerShell 7.2 preview 8 Local date format fails and only US format succeeds.Error details
