1. Problem
The logback log time doesn’t match the system time, always differing by several hours. Setting the project timezone didn’t help, and new Date() in the project shows the correct time.
2. Cause
The same project is deployed on two machines. The time was normal on the previous machine, but not on this one. The specific cause hasn’t been found yet.
3. Solution
Modify the time format in the logback configuration file pattern
Before modification:
<property name="pattern" value="%d{yyyy-MM-dd HH:mm:ss:SSS} %thread [%level] %m%n"/>After modification:
<property name="pattern" value="%d{yyyy-MM-dd HH:mm:ss:SSS,CTT} %thread [%level] %m%n"/>Add a specified timezone after yyyy-MM-dd HH:mm:ss.SSS, separated by a comma. For example, yyyy-MM-dd HH:mm:ss.SSS,CTT. CTT represents Shanghai time. After this change, it works correctly.
