Win32_UTCTime - powershell.one

The Win32_UTCTimeWMI class describes a point in time that is returned as Win32_UTCTime objects that result from a query. These are returned as the value for the TargetInstance property in the __InstanceModificationEvent system class. The Hour property is returned as the Coordinated Universal Time (UTC) time on a 24 hour clock.

Methods

Win32_UTCTime has no methods.

Properties

Win32_UTCTime returns 10 properties:

'Day','DayOfWeek','Hour','Milliseconds','Minute','Month','Quarter','Second',
'WeekInMonth','Year'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_UTCTime -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_UTCTime exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

Day

UINT32

Current day that matches the query (1 31).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Day

DayOfWeek

UINT32

Current day of the current week that matches the query (0 6). By convention, the value 0 (zero) is always Sunday, regardless of the culture or the locale set on the machine.

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property DayOfWeek

Hour

UINT32

Current hour of the current day (0 23).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Hour

Milliseconds

UINT32

Not implemented.

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Milliseconds

Minute

UINT32

Current minute (0 59).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Minute

Month

UINT32

Current month that matches the query (1 12).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Month

Quarter

UINT32

Current quarter of the current year (1 4).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Quarter

Second

UINT32

Current second of the current minute (0 59).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Second

WeekInMonth

UINT32

Current week in the current month (1 6).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property WeekInMonth

Year

UINT32

Current year matching the query (4 digits).

Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property Year

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'Day',
              'DayOfWeek',
              'Hour',
              'Milliseconds',
              'Minute',
              'Month',
              'Quarter',
              'Second',
              'WeekInMonth',
              'Year'
Get-CimInstance -ClassName Win32_UTCTime | Select-Object -Property $properties

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_UTCTime -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”

Get-CimInstance -Class Win32_UTCTime -Filter 'Caption LIKE "a%"' 

Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT Quarter, DayOfWeek, Day, WeekInMonth FROM Win32_UTCTime WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT Quarter, DayOfWeek, Day, WeekInMonth FROM Win32_UTCTime WHERE Caption LIKE 'a%'" | Select-Object -Property Quarter, DayOfWeek, Day, WeekInMonth

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_UTCTime -ComputerName $list 
$result

Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_UTCTime -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use Win32_UTCTime, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_UTCTime was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

Win32_UTCTime lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_UTCTime is implemented in Wmitimep.dll and defined in Wmitimep.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Wmitimep.mof
