This is very common, you must purchase a new clock. From time to time it may come on intermittently, but the clock is still broken. They are ridiculously expensive as well. MSRP $253.63.
Added: These clocks were manufactured as Liquid CrystalDiodes (LCD's) and when they burn out - that's the end of them.

The SRS light on Honda model vehicle are lit when there is a problem in the safety system. To remove the light the vehicle should be taken to an authorized dealership so they can properly diagnose the problem and reset it.
In a 2001 Honda Passport, the clock light is typically controlled by the fuse labeled "Instrument Panel" or "Interior Lights." You can find this fuse in the fuse box, which is usually located under the dashboard on the driver's side or in the engine compartment. If the clock light is not functioning, checking this specific fuse for any signs of a blown filament is a good first step. Always refer to the vehicle's manual for the exact fuse location and specifications.
You cannot replace the clock 'light' on an older CR-V since there is no bulb. It is an L.C.D. (liquid crystal diode) unit which, if it fails, must be replaced.
Usually a problem in the emission control system. Have vehicle scanned to determine the problem
hold boton that says clock then use the preset #4 and 6 for time ajusting
How do you turn off the check engine light on a 2001 honda accord?
Sorry to tell you this - but - if it is the original equipment clock that was built with the car, the chances are 99% that the clock has burnt out. Those clocks were equipped with Liquid Crystal Diodes which have a finite life to them. If the clock is now dark, the odds are greatest that the clock has simply come to the end of its life and needs to be replaced.
It means there is a problem with the ABS (Anti-lock Brake System). Seek professional help.
