Helper class for translating between two times.
The time translator can be configured with a Real start time, a Translated start time, and a time scale.
It will convert a time from a series starting at realStartTime to a comparable time series instead starting at translatedStartTime. All durations in the time-sequence as scaled by 1/(timeScale).
That is, a time-sequence with time-scale 2 will finish twice as quickly.
