How do I make an alarm clock?

haha what a concidence i made a clock that do that couple days ago :)

i did like this; my clock is analog so i just need 12 textures, then i made a animated texture on Mcreator.

The animated texture have a tickrate of 1 in-game hour, so each in-game hour it will jump to next texture, it start at texture 6´Clock (6AM but since my clock is analog it also goes for 18H - 6PM)

Then i made 2 blocks; clock and clockringing, on clockringing i put the animated texture

Then i made a procedure to 'if time = 0' then replace block and 'when block placed' -> Play Sound *(alarm)

let me know if you need more help
