Hello,
Does the function SysTimeRtcGetTimezone from SysTimeRtc library take into consideration summertime and wintertime when there is no connection to the ctrlX CORE?
I mean, today we are in CET (UTC+1) and the bias is 60 min. When the time changes in Europe (this year is march 30th), the hour will switch automatically to CEST (UTC+2) and the bias will be 120?
All of this, considering that there is no connection to the webserver and the ctrlX CORE has no connection to any NTP server.
I am not quite sure what you mean by no connection to a ctrlX CORE. If you are using the ctrlX AUTOMATION - PLC app that is running on a ctrlX OS (in standard installed on a ctrlX CORE) the library function will get its time from the operating system. The system time is buffered by the battery mounted in the ctrlX CORE.
Please have a look to the documentation of the function block itself in the library manager inside the ctrlX PLC Engineering to get to know more about the data given back by the function block:
