Hello samid raif,
I already faced a similar error...
I solved in way:
1º) As you know, the SAP Hana DB is running with <sid_hana>adm user in Linux operation system;
2º) Check the <sid_hana>adm profiles (> cd ~) and the environment variable TZ and put the simbol # (for comment - disable the environment variables) in the following lines in .sapenv.sh and .sapenv.csh files:
# setenv TZ UTC
# export TZ=UTC
3º) Restart the Hana DB and check again the Hana DB hour with the following query in SAP Hana Studio:
SELECT CURRENT_TIMESTAMP “current timestamp” FROM DUMMY
4º) Retry the SAP installation!
BR,
João Dimas
