Where download the Libraries - RTC ds1307

Hello I need to know where I will download the librari RTC ds1307.
Thanks for your help !!!!!

Isn't it part of the TIme library - Arduino Playground - Time -

google gives many hits on DS1307 libraries e.g. Library for DS1307 Real-Time Clock - Libraries - Arduino Forum which points to - GitHub - turicas/DS1307: Arduino library for reading and setting date and time for the DS1307 Real-Time Clock IC

But be aware that there are probably many versions of the lib. IF you have a pre-Arduino 1.0 version you might need some small patches . E.g. the one above uses the old WIRE library calls

A newer and more elaborated one - Google Code Archive - Long-term storage for Google Code Project Hosting. -

BTW a more accurate RTC is the 3231 - GitHub - JChristensen/DS3232RTC: Arduino Library for Maxim Integrated DS3232 and DS3231 Real-Time Clocks
