This is my rewrited version of the original Rtc_Pcf8563 library for Arduino. All credits go to the original authors.

My version differs for

• Rewrited everyting to be for Pcf8593 Real Time Clock (Not Pcf8563 anymore)
• Removed square wave, not supported by Pcf8593
• Added new alarm methods supported by Pcf8593 (daily, weekdays, dated)
• Timer is not supported, because used for saving year
