maybe, until a more powerfull system exists we could simply select
the input with matching type with the finest timebase ?
(one could also pick the largest timebase that allows all timestamps
 of all inputs with same type to be exactly represented, but iam not
 sure this is better with actual real world data)

Rewriting code that is poorly written but fully understood is good.
Rewriting code that one doesnt understand is a sign that one is less smart
then the original author, trying to rewrite it will not make it better.
