Hello! When I write select sessiontimezone from dual, it returns me words. I want the value in numbers. If I use: ALTER SESSION SET TIME_ZONE = '-7:0'; how about the number part? Do I write the exact time I have on clock ? How if I want to go from number to words- and let's say don't know what to write in there (what timezone I am)? Hope U have understood what is messing me_ how to go to other option, without knowing exactly the exact values? (to change JUST the option, without knowing the right values!) Many thanks!!!
