Function Documentation

◆ TIME_SCALE_MS()

const raw_time_64 TIME_SCALE_MS ( lib::time::TimeValue::SCALE/ 1000 )

scale factor used locally within this implementation header.

TimeValue::SCALE (µ-ticks, i.e. 1e6) is the correct factor or dividend when using raw_time_64 for display on a scale with seconds. Since we want to use milliseconds, we need a factor of 1000 to get correct results.

◆ build_time_from() [1/2]

raw_time_64 build_time_from ( FSecs const & fractionalSeconds )

Converts a fraction of seconds to Lumiera's internal opaque time scale.

Parameters

fractionalSeconds given as rational number

Note: inconsistent with Lumiera's general quantisation behaviour, here negative fractional micro-ticks are truncated towards zero. This was deemed irrelevant in practice.
