What do we do: 14198 Time>>print24 prints nanos, though it claims not to

Hi,

what do we do with this:

https://pharo.fogbugz.com/f/cases/14198/Time-print24-prints-nanos-though-it-claims-not-to

We intergrated it even the last comment before integrating started with
"I still don't agree totally (with the solution, I do see there is an issue).”

Do we revert it? Is is good enough?
