Hello Mikko,
I tried reading clock from the meter using DLMS client example in C. everything is fine except the year value. It reads as 120 instead of 2020 or 20. Can you please tell me how can i fix this?
Clock structure screenshot is attached here.
Here is the trace:

Hi,
Hi,
It's correct. Year in tm structure is years since 1900. It's defined on ANSI C standard.
