Module option_millis_i64_trunc 

A time extent as whole milliseconds, truncated on the way out.

Use this module to match an external format that integer-divides and does not round, such as Tempo’s durationMs. Reading is exact, so this module is asymmetric on purpose. See TimeExt::millis_i64_trunc.

The Option form of the sibling module: null is None.
