HourHandPoint is the unit vector of the hour hand at time `t`,. represented a Point.

func MinuteHandPoint

func MinuteHandPoint(t time.Time) Point

MinuteHandPoint is the unit vector of the minute hand at time `t`,. represented a Point.

func SecondHandPoint

func SecondHandPoint(t time.Time) Point

SecondHandPoint is the unit vector of the second hand at time `t`,. represented a Point.
