[FIX] base: float_time

- Record a timesheet entry of '00:14'
  => it is correctly saved as 0.23333...

The tmesheet appears as '00:13'.

This is because `minutes` is equal to `13.99999999999998`, which is
truncated to `13` at formatting.

A simple call to `round` is enough to prevent this. Moreover, we add a
check to convert 60 minutes into an hour. This is similar to:
