Detailed Description

template<typename A, typename B>
class Evoral::TimeConverter< A, B >

A bidirectional converter between two different time units.

Think of the conversion method names as if they are written in-between the two template parameters (i.e. "A <name> B").

_origin_b should be the origin for conversion in the units of B. That is, there is some point in time _origin_b, such that:

to() converts a time _origin_b + a into an offset from _origin_b in units of B. from() converts a time _origin_b + b into an offset from _origin_b in units of A.
