RTC-SCM-CLI: how to detect whether a login is necessary before calling any CLI command ?

1. Execute login command
• Internally, calls lscm.bat with login command (with appropriate username and password)
• As lscm.bat is called for the first time, it launches "scm.exe" which continues to run even after termination of lscm.bat (I assume, this scm.exe is the daemon process that is explained in jazz.net. Please correct me if I'm wrong)
• login command is successfully executed
  
2. Execute "create stream" command
   
• Internally, calls lscm.bat with "create stream" command (with appropriate arguments)
• Stream gets created successfully from the account of the user who logged-in during step-1
  
3. ....
   
4. User continues to execute other commands of lscm.bat
5. User executes logout command
   

Questions:

1. Is there a possibility that the user might get automatically logged out during steps 2 to 4, in case if these steps are executed in longer intervals ? Say, the user executes step-2 today, but doesn't close the wrapper tool application, and doesn't shut down the PC, then executes step-3 one day later.
   
• Internally, is there a timeout defined for automatic logout ?
• if yes, how to detect this auto logout, so that login command can be issued before executing the actual command intended by the user in step 2 to 4 ?
• if not, are there any other scenarios during which the user credentials might be lost ?
  

Thanks for your help in advance.
