DS1307 are interfaced as a time keeping device, usually in the form of an Integrated Circuit (IC). Real-time clock (RTC) is like a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. This module uses the RTC DS1307 IC and an extra EEPROM chip for farther use.
Real Time Clock ICs are present in computers, servers, and many embedded systems and in fact they are used wherever it is required to keep an accurate time.
