/**
 * Returns a duration in the nearest whole-number units like "999 µs" or "  1 s ". This rounds 0.5
 * units away from 0 and 0.499 towards 0. The smallest unit this returns is "µs"; the largest unit
 * it returns is "s". For values in [-499..499] this returns "  0 µs".
 *
 * The returned string attempts to be column-aligned to 6 characters. For negative and large values
