Date comparison does not work
I am attempting to write a file detection script, but PowerShell doesn't seem to recognize that the file dates are equal. Here's what I'm experiencing:
PS C:\> $FileDate = Get-Date -Date "2023-05-08T11:00:31"
PS C:\> $FileDate
Monday, May 8, 2023 11:00:31 AM
PS C:\> $FileDate.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True DateTime System.ValueType
PS C:\> $TestDate = (Get-Item 'C:\Windows\System32\drivers\etc\hosts').LastWriteTime
PS C:\> $TestDate
Monday, May 8, 2023 11:00:31 AM
PS C:\> $TestDate.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True DateTime System.ValueType
PS C:\> if ($FileDate -eq $TestDate) {$true} else {$false}
False

Found the problem. Here's the fix:
$TestDate = (Get-Date -Date '2023-05-08T11:00:31').DateTime $FileDate = ((Get-Item '%redacted%').LastWriteTime).DateTime if ($FileDate -eq $TestDate) { Write-Host "Detected" Exit 0 } else { Write-Host "Not detected" Exit 1 }
