Robert,
There is theory (the hardware being used) vs the code accessing the hardware.
Fact: the hardware clock does not use more power just because there is a visible clock on the e-ink display.
Poorly written "display time" code, that should be asleep unless a screen refresh is called for, may keep the other CPU from sleeping (or causing frequent wakeup's).
I am guessing the latter.
