It appears that we do not have a consensus on this.

Reasons for parameterizing with precision _and width_:
- It's more flexible and probably future proof.
- Would allow for 64-bit time values. Is this _really_ required for the
imote2?
- Would allow for 16-bit time values, to save some space in the message
payload.

Reasons against it:
- Sources would get more verbose.
- LocalTime is not parameterized by width, either. To access non-32-bit
local time, a custom interface would be required anyway.
