docstring: Convert the given time duration in the given unit to this
  unit.  Conversions from finer to coarser granularities
  truncate, so lose precision. For example converting
  999 milliseconds to seconds results in
  0. Conversions from coarser to finer granularities
  with arguments that would numerically overflow saturate to
  "-PHP_INT_MAX -1" if negative or "PHP_INT_MAX"
  if positive.
  
  For example, to convert 10 minutes to milliseconds, use:
  TimeUnit::MILLISECONDS()->convert(10, TimeUnit::MINUTES);
  
  @param int $sourceDuration the time duration in the given source unit
  @param TimeUnit $sourceUnit the unit of the source duration argument
  @return float|int
