"Time of Day" Clocks should emit a Redstone Output at the time of "Bed Wakeup", for the sake of calibrating Player-Made Clock Displays

Current attempts at making functional Redstone Clock Displays are hindered by a distinct lack of a reliable calibration signal from which to estimate the current time to any reasonable accuracy. In addition, the Player(s) being able to randomly reset the time by going to bed further complicates calibration of Redstone Clock Displays. Even the most regular of Redstone Clock Circuits needs its output to be Calibrated after every Bed Wakeup, and even with a frequent Redstone Output, the "Time of Day" Redstone Clock available via Crafting needs to have an identifiably unique Redstone Output signal to recalibrate the output of Redstone Clock Displays. Please have the "Time of Day" Redstone Clock emit a calibration signal at the time of Bed Wakeup, so players can get to work on what their Redstone Clock Display looks like, rather than how it's calibrated.

On the subject of "Time of Day" Redstone Clocks emitting a repeating signal over the course of a day, I recommend something along the lines of a De Bruijn sequence, with the longest output serving as the calibration signal.
