TimeBucketAction isFloorable restriction

[tonypizzicato]

Hi! I've stuck with the problem trying to implement custom granularities in my pivot-based app.
I want to add an input to set custom time periods, e.g. P15D, P3W and so on.

But i've found that TimeBucketAction has a condition in it's constructor duration.isFloorable() that depends on siblings field for different shifter (60 for seconds and minutes, 24 for hours, 12 for month and so on), but days and weeks have no siblings at all, so i can't set any value for days other than 1.

So, I have two questions:

1. Why is there such a restriction and why i can's set values for days other then 1(first thought that there can be different number of days in a year)?
2. Is there some solution to set custom time periods?

Thank you!

I am also trying to achieve time granularity like P2D, PT18H etc, but duration.isFloorable() returns false.

@vogievetsky any help or suggestion on how to approach this? Given this issue was there 18 months back as well
