|%z| thouthand's fractions of second (= milliseconds), ex. 25 ms -> 25|
|%fff| thouthand's fractions of second (= milliseconds), with leading zeros, ex. 25 ms -> 025|
|%ff| fractions of milliseconds rounded to hundreds, with leading zeros, ex. 125 ms -> 13|
|%f| fractions of milliseconds rounded to ten's, ex. 125 ms -> 1|

**Example**
<code pcmi>
TimingFormat('%hh:%mm%:%ss.%fff', 183353) → '00:03:03.353'
