Missing documentation how to invoke custom handler with timeTrigger binding

Dear Azure Team,

In all the comm, missing is how to invoke in this new and beautiful world custom handler with timeTrigger binding.
There is quite a bit of documentation that is currently published on MSDN and which already in conflict with how to handle Azure Function with custom handler, what options and such.
While teams at Microsoft like having narrow focus around assigned target, it does appear to unencumbered with internal Microsoftee politics outsider, that the work on this isolated worker created quite a bit of impact on overall Azure Function infrastructure, so, while I do expect you to punt my ask, I believe this is the proper starting point to query.
Please share if you know the proper channel to direct same question -
what is the new / updated guidance to deploy custom handler with timeTrigger on Azure Function. Needless to say, I have already searched this repository for any mentioning of time trigger and tried to get some sense using --help parameter to func.exe CLI tooling to no avail.
