先说问题，我创建了一个Lead，创建时间14:21， TimeZone is UTC+8.
我期望的修改日志显示的时间也是14:21, 结果错误的显示成了CET time(有六个小时的差异).
解决方案
加上下面的时间戳转换，把SAP Netweaver系统里的时区设置考虑进去。
Make clear there is two Personal Time Zone in the backend (User Time Zone and System Time Zone).
Key Point
Make clear to the time convert during backend and frontend.
(1) In DB, it’s UTC time.
(2) In OneOrder, after select data from DB, we use below function, convert the UTC time to User Time Zone.
(3) In our program, we can’t transport User Time Zone out to UI directly, we should convert User Time Zone to UTC and update it_ausg. (it’s better for UI to convert UTC to your browser time)
(4) In the frontend, we can just use one logic, convert UTC to local time.
