Hello everyone! I made a clock using RTC1307 module and as it doesn't automatically autocorrect time I have to correct the time . My current time and date is set to 12:00 AM 0/0/1970. I want to know how to set it to present time

Sir, I have a battery on the RTC. I'm new to Arduino as well. This was my first Arduino project. Can you please tell me how to correct the time ? I have a battery in the RTC .
