It seems that the problem lay in the fact that the operations aren't precomputed
by the separate macros but, rather, dropped in to form a larger equation. The
result is that I had to parenthesize EVERYTHING in each macro, so that the
proper order of operations could be preserved.
It makes sense when I think about it.
the troublemaker line was in the eClock macro
_TICK_*Seconds
i changed it to (_TICK_*Seconds) and voila!
I also put encapsulating parentheses around each of the three formulae in Timer.
The Timer macro is now self-limiting and additive so that the line:
rotate (Timer(1, <0, 0, 0>, <0, 0, 5>, 1080) +
Timer (3, <0, 0, 5>, <0, 0, 10>, 1080))*x
creates a timeline for rotation about the x axis where the first five seconds
are spent accelerating to 4 revs/sec and the last five are spent rotating at a
constant 4 revs/sec.
