Google browser Problems

Google browser problems last night using google browser to enter the password has not been successful. I thought it was the one that broke down. in the end, it was successful to go to 360. amazing B. I went to the background to clear the cache and it was successful. does google tamper with our webpage? Amazing. No. SET the database Time Format this morning with alter session set NLS_DATE_FORMAT = 'yyyy-mm-dd hh: mm: ss'; always reported error: SQL error: ORA-01810: format code appears twice at last, click it one by one to see a hh: mm: ss error. it should be hh: mi: ss! Correct statement: alter session set NLS_DATE_FORMAT = 'yyyy-mm-dd hh: mi: ss ';
