-Like utime(), but allows time resolution down to the nanosecond. Currently
-times are passed as "numeric" (internally I believe these are represented
-typically as "long double"), so the sub-second portion is represented as
-fractions of a second.

-Note that if this call is implemented, it overrides utime() ALWAYS.

-Also note that if you want times passed as arrays instead of floating point
