Chronometer Sensor

The Chronometer Sensor is a sensor block added by GregTech 6 which measures the time of day in Minecraft minutes. It always measures time on the Overworld, even if placed in another dimension.

Usage
Sensors can be rotated with a Wrench horizontally. A Monkey Wrench can be used to specify which of the five non-front sides reads the adjacent block space. Both tools display the helper grid, but respond to the area clicked on the thin model itself.

Using a Screwdriver on the upper display section toggles between decimal and hexadecmial notation. Using the Screwdriver on the lower right icon section (or any rim) rotates between sensor modes: Most of these modes will cause the sensor block to become redstone powered under certain circumstances. While in any of the four compare to set point modes, the set point can be changed by clicking on the six buttons in the lower left with a useless item or empty hand, in the same way as the Screwdriver would change the averaging window.

Behaviour
The value being measured is scaled to the length of the Minecraft day, so unlike other sensors no value overflow is possible. It does not conform to any number of Ticks, nor to real-life seconds; rather the unit represents one 1440th of the day length, like a minute does to a day.

The zero point is offset from Minecraft's internal day/tick counter, being set to zero at midnight like a normal real world clock. However, it is tied to the internal day count, so mods that move the sky sphere are not taken into account. It similarly has no relation to local day/night on other worlds, and all Chronometer sensors in every dimension will be advanced by sleeping or otherwise skipping time in the Overworld.

Using the Screwdriver on the six buttons in the lower left increases or decreases the averaging period for readings, but has no effect on the reading; time flows smoothly unless skipped.
