I am using axios in react js to send data in put request. it was working perfectly but when I tried to send current datetime with put request its giving me error .

Bad Request: /buyer/OrdersAPI/14/
[03/Oct/2021 14:19:44] "PUT /buyer/OrdersAPI/14/ HTTP/1.1" 400 132

I have to post current date and time to rest api date time field

My code

const api = axios.create({
    baseURL: 'http://localhost:8000/buyer/'
})

updateOrderStatus = async(id,status) => {
        let data = new FormData();
        data.append('status',status );
        data.append('orderStartTime',Date())
        await api.put(`OrdersAPI/${id}/`, data);
        this.getNewOrders();
    }

if I console.log(Date()) its giving me Sun Oct 03 2021 14:28:59 GMT+0500 (Pakistan Standard Time)
