Updated version of the library attached. Main changes are:
Configuration option allows the Watch-Dog Timer to be used for the RTC instead of TimerA. This also requires replacements for the functions in wiring.c. A side effect caused by limitations of the 430 hardware is that delay, millis and micros only have a resolution of 1.9mS.
Added helper functions to convert the hmsDMY time into UnixTime format, return day-of-week, etc.
Added an alarm class.
