Abstract: In some embodiments, an advisory time keeping device may include a housing having a controller, a control input, a display output, and a tilt sensor. The controller may include a timer module and a memory. The control input may be operable to enter time data and advisory data into the memory. A display output may be coupled to the housing which may be operable for displaying data from the timer circuit and memory. The tilt sensor may be in communication with the controller, and the tilt sensor may be operable to detect changes in the orientation of the housing. The controller may be operable to cause the display output to display advisory data in response to changes in the orientation of the housing which may be detected by the tilt sensor.
