Crontab is not executed after the time zone is adjusted

Today, I wrote a script on VPs to back up data to Baidu disk (for more information, see here ). After writing, you want to use crontab to make a timer. The test fails. It took me half a day to remember that the VPs was changed to the time zone. CP/usr/share/zoneinfo/Asia/Shanghai/etc/localtime was used for modification.
Modify/etc/sysconfig/clock as described on the Internet.

Zone = "Asia/Shanghai" UTC = false (set to false if UTC time is not used) arc = false

Restart crond

/Etc/init. d/crond restart

Easy to use: d
