Hi Luc,
Thanks for your recommended to upgrade PowerCLI version. Now I am using powerCLI 5.0 and already passed the command: "$dts = Get-View $esx.Extensiondata.ConfigManager.dateTimeSystem".
But another issue has appeared with the command: "$dts.UpdateDateTime(Get-Date)". Error as below:
Missing ')' in method call.
At line:1 char:26
+ $dts.UpdateDateTime( <<<< get-date)
+ CategoryInfo : ParserError: (CloseParenToken:TokenId) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingEndParenthesisInMethodCall
