Then, you can use the _tounixtimestamp function by requiring fs-extra and calling the function with a Date object as its parameter:

index.tsx
const fs = require('fs-extra');

// Create a new Date object
const date = new Date('2022-01-01T00:00:00.000Z');

// Convert the Date object to a Unix timestamp with _tounixtimestamp
const timestamp = fs._tounixtimestamp(date);
console.log(timestamp); // Output: 1640995200

Note that the _tounixtimestamp function returns the Unix timestamp as a number representing the number of seconds since the Unix epoch (January 1, 1970, 00:00:00 UTC).
