How to make a clock sound?

Questions about producing? Ask them here.
Ok, I'm not an expert musician. I'm a programmer and I'm making a game, and I would like to make a clock sound. I searched the sound in the program but until now I have not found it (I don't know if the sound exists in the program).

If someone can tell me what sound or instrument to use, I would appreciate it.
Thanks.
Go to Freesound.org and type clock in the search sounds box. Hundreds and hundreds to choose from.

Or you can listen to a clock and try to synthesize something similar.

What sound or instrument to use?

If by "clock", you speak of the "tic tac" of the seconds hand, I believe that any synth would do it.
Personally, I would use the TripleOsc, the Kicker or ZynAddSubFX.

I guess it's also possible to get a satisfactory result from any LMMS sample.

Alternatively, you can record the clock yourself (preferably in a quiet room).
Ok, I found some good sounds on the page, but I will also try to make the sound by myself.
Thanks to both.
