Could Not Find Mandatory Parameter TimeZone

[richardjgreen]

I've created a really simple DSC Configuration using this module to configure the time zone of a machine.
`Configuration SetRegionalSettings {

Param
(
    [Parameter(Mandatory = $true)]
    [ValidateNotNullorEmpty()]
    [String]$NewTimeZone
)

Import-DscResource -ModuleName rsInternationalSettings

rsTime SetTimeZone {
    TimeZone = $NewTimeZone
}

}

SetRegionalSettings -NewTimeZone "GMT Standard Time"`

When I run Start-DscConfiguration to enact the MOF file, I get the error Could Not Find Mandatory Parameter TimeZone. When I look inside the MOF file, TimeZone is set to NULL. As you can see from my example, I am clearly defining a value for TimeZone so I think there is a problem with the rsTime module not passing this value through.
