Hello,

In Wincc Alarm Logging, There is no problem at other alarm list's date and time but Process alarm date and time seen 1995? How can i change this?

There are two ways, you can configure time synchronization (the better way) or you can set the time manually.

For time synchronization have a look in the Engineering System manual: https://support.industry.siemens.com/cs/ww/en/view/109754984

Setting the time manually is quite easy, but be careful if you use tag/alarm archives, because you change the time from 1995 to 2018:

1. Open the HW Config
2. Select the CPU and click in the menu "PLC" on "Set Time of Day".
3. A window will be opened and there is a button for setting the time of the cpu.
