Procrastinator

A procrastinator is a device that taps into the river, or perhaps ocean, of the time dimension of the space-time continuum.

The procrastinator was invented by Joe, founder of the Time Ninjas' Dojo, which now has a cavernous hall like a factory full of procrastinators. A procrastinator is a standing cylinder on an axle, and the rolling of the cylinder can "wind in" or "wind out" time much as a spool can be used to wind yarn. Stone procrastinators the size of pillars are used to slowly wind a large amount of time (up to millions of years). Procrastinators vary by size and material, down to small chalk cylinders that spin quickly to precisely wind time in seconds. Trained drivers in the hall of procrastinators switch each of the procrastinators between winding in and winding out, to give areas of the world and history the time that they need, and to compensate for localized time anomalies. When there is a severe time anomaly, the procrastinators may cut loose and almost randomly wind time in and out on their own. In such a situation, a very experienced or very clever driver is needed to couple the procrastinators in pairs of winding time in and out at the same speed, to achieve overall balance.

These device are evocative of mechanical flywheels, cylinders or discs that can store or release kinetic energy, thereby spinning faster or slower.

A portable model of procrastinator, that can be worn as a backpack, and can cut in to supply time if a Time Ninja on a mission needs more time has been defeloped. This type of procrastinator is powered by a wind-up spring.

Annotation
From the pen of the prolific Real-life eighteenth century English poet (1683 - 1765):

''Procrastination is the thief of time: '' Year after year it steals, till all are fled, '' And to the mercies of a moment leaves  The vast concerns of an eternal scene.
