getOSTimeZone

public static Map<String,String> getOSTimeZone()
                                        throws IOException,
IndexOutOfBoundsException,
ShellException,
InterruptedException

Retrieves the OS Time-zone

Returns:

a Map of Time-zone properties and values mentioned in the class description

Throws:

IOException - re-throws the exception thrown by CIM_ML.getPropertiesAndTheirValues(String, String) when there are I/O Errors during streaming of data from and to Powershell and other generated files

IndexOutOfBoundsException - re-throws the exception thrown by CIM_ML.getPropertiesAndTheirValues(String, String) when there is a parsing error of data fetched from Windows Powershell

ShellException - if any internal command used in the powershell throws errors

InterruptedException - if the thread waiting for the process to exit, gets interrupted. When catching this exception, you may re-throw it's interrupted status by using Thread.currentThread().interrupt();

While catching any of the Exceptions, you may return an empty Map to avoid any NullPointerException that might get thrown because your variable might be expecting a string. However, this does not make you immune from the NullPointerExceptions that may be thrown in case of powershell output format changes in the future, causing the underlying parsing logic to fail.
