Whenever you have a true DateTime (and not a string, for example), you have plenty of powerful ways to format. You can get DateTime objects directly:
PS> $installDate = (Get-CimInstance -Class Win32_OperatingSystem).InstallDate PS> $installDate.GetType().FullName System.DateTime
Or you can convert a string to a DateTime:
PS> $psconf = Get-Date -Date '2019-06-04 09:00' PS> $psconf.GetType().FullName System.DateTime
Once you have a DateTime object, use the ToString() method and supply one or two arguments.
The first argument determines which parts of the date you want to see, and uses these (case-sensitive!) placeholders:
y Year
M Month
d Day
H Hour
m Minute
s Second
f Millisecond
The more placeholders you specify, the more detail you get:
PS> (Get-Date).ToString('dd')
30
PS> (Get-Date).ToString('ddd')
So
PS> (Get-Date).ToString('dddd')
Sonntag
PS>
(as you can see, PowerShell uses your default language which was German in this example)
To output a DateTime in ISO format, try this:
PS> $installDate = (Get-CimInstance -Class Win32_OperatingSystem).InstallDate
PS> $installDate.ToString('yyyy-MM-dd HH:mm:ss')
2018-06-08 18:24:46
PS>
If you’d like to also specify the locale (language), specify a CultureInfo as second parameter:
PS> (Get-Date).ToString('dddd', [System.Globalization.CultureInfo]'en-us')
Sunday
PS> (Get-Date).ToString('dddd', [System.Globalization.CultureInfo]'zh')
星期日
PS> (Get-Date).ToString('dddd', [System.Globalization.CultureInfo]'es')
domingo
PS> (Get-Date).ToString('dddd', [System.Globalization.CultureInfo]'fr')
dimanche
PS>
If you’re wondering what the culture identifier is for a given culture, try this:
PS> [System.Globalization.CultureInfo]::GetCultures('Installed') | Out-GridView -PassThru
