Convert Dates in Powershell but Format Not Recognized-CodePudding

I'm trying to use powershell to convert a string that contains RFC 2822 formatted dates into another format. Right now I'm getting an error saying my string was not recognized as a valid DateTime.

Write-Host ([Datetime]::ParseExact('Thu Oct 07 09:23:26 UTC 2021', '[R][1]', $null)).ToString("yyyyMMdd")

I'm not sure what I'm doing wrong.

CodePudding user response：

The R standard datetime format string specifier does not describe the format you've supplied.

You're gonna need a custom format string:

[Datetime]::ParseExact('Thu Oct 07 09:23:26 UTC 2021', 'ddd MMM dd HH:mm:ss UTC yyyy', $null)
