# Epoch

This Go code demonstrates working with the `time` package to obtain Unix timestamps at different precisions. Let's go through the code with inline comments and explanations:

```go
// Importing necessary packages.
import (
	"fmt"
	"time"
)

// The main function, where the execution of the program begins.
func main() {
	// Getting the current time.
	now := time.Now()
	fmt.Println(now)

	// Converting the current time to Unix timestamp at different precisions.

	// Unix timestamp in seconds.
	fmt.Println(now.Unix())

	// Unix timestamp in milliseconds.
	fmt.Println(now.UnixMilli())

	// Unix timestamp in nanoseconds.
	fmt.Println(now.UnixNano())

	// Converting Unix timestamp back to time.Time.

	// Creating a time.Time from Unix timestamp in seconds.
	fmt.Println(time.Unix(now.Unix(), 0))

	// Creating a time.Time from Unix timestamp in nanoseconds.
	fmt.Println(time.Unix(0, now.UnixNano()))
}
```

#### Output

```
2024-01-24 13:21:47.6288203 +0530 IST m=+0.001548401
1706082707

```

Explanation:

1. **Getting Current Time:**
   * `time.Now()` returns the current time.
2. **Unix Timestamps:**
   * `Unix()` returns the Unix timestamp in seconds.
   * `UnixMilli()` returns the Unix timestamp in milliseconds.
   * `UnixNano()` returns the Unix timestamp in nanoseconds.
3. **Converting Unix Timestamps Back to time.Time:**
   * `time.Unix()` is used to create a `time.Time` instance from a Unix timestamp.
   * The first argument is the number of seconds, and the second argument is the number of nanoseconds.

This code showcases how to obtain and convert Unix timestamps using the `time` package in Go. It's useful when you need to work with timestamps in different precisions and convert them back to `time.Time`.
