Hello all.
After upgrading OS on Exadata dbnodes from OEL6 to OEL7, all corresponding databases were started with UTC time zone and "local" timezone was ignored.

So, the sysdate and systimestamp returns date in UTC instead of PST.
No changes in srvctl envs, server env variables, $GRID_HOME/crs/install/s_crsconfig_$HOSTNAME_env.txt were done.
