Thx.

There is another patch.
It works, but one thing is wrongly done because I lack knowledge.

Where I'm using DirectFunctionCall3 I need to pass the timezone name, 
but I'm using cstring_to_text and I'm pretty sure there's a memory leak 
here. But I need help to fix this.
I don't know how best to store the timezone in the generate_series 
context. Please, help.
