DS1307 Real Time Clock Module

This real time clock module is based on the DS1307 chip which supports the I2C protocol. The clock and calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either a 24-hour or 12-hour format with AM/PM indicator.
