I made a clock in mbed. mbed has RTC built-in. A convenient function is prepared for in the rtc_time function group of mbed.h. Because data are provided at the time when they give unix timestamp and ask it at suitable distance, a format to like it can be set and displays it to LCD. If unix timestamp is provided from web, it becomes more convenient. See: http://blogs.yahoo.co.jp/jf1vrr_station/19803647.html (Japanese)
