For imprecise fields, the unit size is variable, and so this method returns a suitable average value.

BaseDurationField
If the milliseconds is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
The default implementation returns
Utils.safeToInt(getAsLong(millisDuration, instant))
