I want to make a bot with discord.js v12 to count how many time a user has a role and then send it in a channel with a webhook. My problem is how to make it counting time. Here is my code:

if(command === 'on') {
        const role = message.guild.roles.cache.find(role => role.name === '🚀On Duty')
        message.author.send('You are on duty')
        message.member.roles.add(role)
        message.react('<:tick:902920026489749564>')
    } else if(command == 'off'){
    const role = message.guild.roles.cache.find(role => role.name === '🚀On Duty')
    message.member.roles.remove(role)
    let seconds = Math.floor(message.member.roles.cache.has(role.id) / 1000);
    let minutes = Math.floor(message.member.roles.cache.has(role.id) / 60);
    let hours = Math.floor(message.member.roles.cache.has(role.id) / 60);
    let days = Math.floor(message.member.roles.cache.has(role.id) / 24);

    seconds %= 60;
    minutes %= 60;
    hours %= 24;

    const wc = new WebhookClient('MyWebhookId', 'myWebhookUrl')
    const log = new Discord.MessageEmbed()
    .setTitle('DUTY LOGS')
    .setDescription(`Username: <@${message.author.id}>\n`
    + `Days: **${days}**\n`
    + `Hours: **${hours}**\n`
    + `Minutes: **${minutes}**\n`
    + `Seconds: **${seconds}**`)
    .setTimestamp()
    .setColor('#fa0505')
    wc.send({
        username : message.author.tag,
        avatarURL : message.author.displayAvatarURL({ dynamic : true }),
        embeds : [log]
    })
    message.react('<:tick:902920026489749564>')
}

It gives me that answer when I type !off
