Pop quiz: what time was it?

Here’s a small quiz derived from some incorrect advice from an AI coding assistant.

package main

import (
    "fmt"
    "time"
)

func main() {
    fmt.Println(time.Now())
    defer fmt.Println(time.Now())
    time.Sleep(10 * time.Second)
}

This program prints two timestamps; will they be

a. Roughly the same time (ie, the same second)
b. Roughly 10 seconds apart
c. Something else

Answer after the fold
