I have this code that calculates in 1 second in 1 second between a certain time and then insert into a table. Instead of calculating every 1 second, how can I calculate, for example, every 5 seconds?

for y = horaInicial, horaFinal-1 do
    hora = tostring(math.floor(y / (3600)))
    minuto = tostring(math.floor((y - hora * (3600)) / (60)))
    segundo =  tostring(math.floor(y - hora * (3600) - minuto * (60)))

end

Just add a third parameter to for indicated the jumps that should be given. So:

function str2time(hora) 
    return tonumber(string.sub(hora, 1, 2)) * 3600 + tonumber(string.sub(hora, 4, 5)) * 60 + tonumber(string.sub(hora, 7, 8))
end

hora_array = {"20:03:02", "20:03:35"}
horaInicial = str2time(hora_array[1])
horaFinal = str2time(hora_array[2])
hora_array = {}
for i = horaInicial, horaFinal - 1, 5 do --note o 5 aqui --------------------------
    hora = math.floor(i / 3600)
    minuto = math.floor((i - hora * 3600) / 60)
    segundo =  math.floor(i - hora * 3600 - minuto * 60)
    table.insert(hora_array, string.format("%02d:%02d:%02d", hora, minuto, segundo))
end

for i, v in ipairs(hora_array) do print(v) end
