Hello AutoGen_2037248 PLC Alarms and other timestamps that comes from PLC are send by Systemtime of the PLC (UTC). In WinCC the Local time is build by the UTC (Time Synchronisation from PLC) and the local settings like timezone and summer/wintertime (if you have). The HMI alarms (descrete and analog) uses the systemtime-timestamps of the HMI. In the Alarm logfile only UTC timestamps are stored. But in the alarmcontrol the HMI calculates its local time and you should see the correct one. So to get a full working Time synchronization and all correct timestamps on both sides you have to use a Time synch in the HMI connection (slave). then set up the same Timezone on PLC and HMI And then use the workaround for Summer/Wintertime (panel does not switch automatically!)
