Jacques Nadeau commented on ARROW-617:
--------------------------------------
I propose two:
32bit micro and 64bit nano.
Agree with simplicity. However, I also think that paying for an extra 4 bytes
for the rare case is suboptimal.
I'd be surprised if the base 10 shift for the other versions would be a huge
problem for most systems.

> 2 options:
> - Use 64 bits for microseconds and nanoseconds, 32 bits for other units
> - Use 64 bits for everything
> The latter is simpler to implement, the former saves space.
