I populated the real time clock and with a bit of minimal testing, it appears to work The clock is completely optional of course, you don't need to bother with it if you don't want one.

The parts list for RTC:
U5 or U6: RTC62421/RTC72421/RTC62423/RTC72423
C10 or R7: 47K-100K 0805 resistor (yes a resistor!)
C12: 100nF 0805 capacitor
C13 or C19: >=2.2μF >=10V 0805 or 1206 tantalum
R1, R2, R3: 10K 0805 resistor
R4, R5: 220-470 0805 resistor
D1: BAT721C or BAT54C diode
Battery Holder: Some cheap ebay one.
