Making sure my linux system does not wake up on suspend

Had this annoying problem in my linux Xubuntu 20.04 when putting on suspend the system then starts even though I put it in suspend and sleep. Using acpitool to turn off wake-up from unnecessary devices. But the problem the change is not permanent and does not survive a restart. So I used cron @reboot to make sure it is always off: @reboot acpitool -W 3 && acpitool -W 9 && acpitool -W 10 && acpitool -W 17 && acpitool -W 63 && acpitool -W 64 && acpitool -W 66 && acpitool -W 68 && acpitool -W 74    

MySQL Test Timezone Script

 CREATE TABLE tzt( id MEDIUMINT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY, ts TIMESTAMP NOT NULL, dt DATETIME NOT NULL ); SELECT @@global.time_zone, @@session.time_zone; SET GLOBAL time_zone = 'Asia/Jerusalem'; SET SESSION time_zone = 'Asia/Jerusalem'; INSERT INTO tzt SET ts='2021-08-22 13:30:00', dt='2021-08-22 13:30:00'; SELECT * FROM tzt\G SET GLOBAL time_zone = 'America/Sao_Paulo'; SET SESSION time_zone = 'America/Sao_Paulo'; SELECT * FROM tzt\G
