Descriptions of time altering apparatuses for removing a need for leap seconds are provided. Currently leap seconds are applied to Universal Time Coordinated (UTC) in order to align UTC with mean solar time. In one embodiment a time measurement system is connected to a gigantic heavy flywheel positioned at at least one of a north rotational pole or south rotational pole of the Earth. The time measurement system may determine a shift of UTC away from mean solar time and may subsequently speed up or slow down the flywheel to adjust a rotational speed of the Earth in order to move UTC back to mean solar time. In a second embodiment a similar time measurement system may raise or lower heavy weights into mine shafts drilled at or near the equator of the Earth for a similar effect. Planetary speed adjustments may be written to a blockchain.

An optical measurement device configured for connection to an industrial network, the industrial network functioning to synchronize time between a master device and a slave device, the optical measurement device includes: an interface module configured to receive a synchronization signal transmitted on the industrial network from the master device within a fixed communication cycle; and a measurement unit configured to perform optical measurements in a measurement cycle. The measurement unit synchronizes when a measurement is taken with the communication cycle in accordance with the synchronization signal received by the interface module.

A method according to one embodiment includes generating, by at least one sensor, motion data indicative of motion of a door having a door closer as the door is moved from an open position to a closed position, analyzing the motion data to determine a duration the door was in each of a plurality of door movement zones between the open position and the closed position, determining at least one adjustment to the door closer for a successful installation of the door closer based on the duration the door was in each of the plurality of door movement zones, and displaying at least one installation instruction corresponding with the at least one adjustment on a graphical user interface of a mobile device.
