The pre-check installation returns the error: Unable to retrieve DB Timezone, refer to checkinstall.log for details when upgrading to v14.2 to 15.1

Steps to Reproduce:

1. On the CA PPM server set the timezone to (UTC) Dublin, Edinburgh, Lisbon, London 
2. On the MS SQL Database server set the timezone to (UTC) Dublin, Edinburgh, Lisbon, London
3. Set the clock to a GMT date for both CA PPM & Database server
4. Extract the install.jar from the CA PPM 15.1 installation media 
5. Run the Install.bat/.sh

Environment

3. Run the install.bat/.sh to proceed with the upgrade.
