Issue with Timezone within ComputerManagementDsc Module shown in example

Hello,

I have copied the example of Set Timezone within ComputerManagementDSC module.
I saved this as a PS script and whenever i run this via azure automation services then it throws me an Error that Timezone is not a valid parameter.

Configuration TimeZone_SetTimeZone_Config
{
Import-DSCResource -ModuleName ComputerManagementDsc

Node localhost
{
    TimeZone TimeZoneExample
    {
        IsSingleInstance = 'Yes'
        TimeZone         = 'W. Europe Standard Time'
    }
}

}

Request you to kindly help me on this.
I am new to Powershell and trying to get more into this.

Exception calling "NewScriptBlock" with "1" argument(s): "At line:8 char:9 + TimeZone TimeZoneExample + ~~~~~~~~ Undefined DSC resource 'TimeZone'. Use Import-DSCResource to import the resource." (At line:8 char:9 + TimeZone TimeZoneExample + ~~~~~~~~ Undefined DSC resource 'TimeZone'. Use Import-DSCResource to import the resource.)

Start with the reported TimeZone example and the ComputerManagementDsc module imported by Azure Automation. Check whether the TimeZone resource is available in that environment and compare the module version with the example. Done means the documented configuration is accepted and runs successfully in Azure Automation, or the compatibility limitation is documented.
