I’m trying to keep this code of mine coming back in real time

Question

I am with a saving command and wanted that when the user, who already used the command, wait 30 minutes but the code returns an error informing remaining time to use the command again as I do ?

const cooldown = new Set();
const db = require('quick.db');
const ms = require('ms');

module.exports.run = async (client, message, args) => {
    if(!message.content.startsWith(','))return;  

    const user = message.author;
    const author = await db.fetch(`work_${message.guild.id}_${user.id}`)

    const timeout = 1800000;

    if (author !== null && timeout - (Date.now() - message.author) > 0) {
        const time = ms(timeout - (Date.now() - message.author));
    
        if (cooldown.has(message.author.id)){
        message.channel.send(` ${user} | <a:negado:872682572965118033> Você já trabalhou hoje,Tente denovo em **${timeout} minutos**`)
      } else {

        const replies = ['Programador','Construtor','Bancário','Motorista','Chefe','Mecanico']

        const result = Math.floor((Math.random() * replies.length));
        const amount = Math.floor(Math.random() * 1000) + 1;
        message.channel.send(` ${user} | <a:azul:876222068688052315> Você trabalhou como **${replies[result]}** e Ganhou Salario De **${amount}** `)
        
        db.add(`money_${message.guild.id}_${user.id}`, amount)
        db.set(`work_${message.guild.id}_${user.id}`, Date.now())
        cooldown.add(message.author.id);
        setTimeout(() => {
            cooldown.delete(message.author.id)
        }, `${timeout}`);
    };
}
}
