Steps to Reproduce:

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

CA PPM 14.2, 14.3,14.4,15.1
