Change "Update distribution points on a schedule" in SCCM 2007 via powershell script

Question

Hi
I would like to change the Custom Schedule start time in the "Update distribution points on a schedule" on a package in SCCM 2007 with out logging into the SCCM console.
I have following line code to query the package.
Get-WmiObject
-Namespace
"Root\SMS\Site_$sitecode"
-Query
"SELECT * FROM SMS_PackageBaseclass WHERE PackageID='$PackageID'"
-ComputerName $ServerName
The problem is I only get the "SourceDate" and "LastRefreshedTime" from the query. I am not sure if I change the "LastRefreshTime" that it would change the start time in the Custom Schedule

Hi Jason
I progressed a little bit with you help. I now have the following bit of code.
$Package = Get-WmiObject  -class SMS_Package -Namespace "Root\SMS\Site_$sitecode" -Filter "PackageID='$PackageID'" -ComputerName $ServerName
$RefreshPkg = $Package.RefreshSchedule()
$RefreshPkg.RefreshSchedule
I get the following error:
Method invocation failed because [System.Management.ManagementObject] doesn't contain a method named 'RefreshSchedule'.
At line:7 char:1
+ $RefreshPkg = $Package.RefreshSchedule()
