There may be something else in your code that is accidentally wrong.
For debug, try printing time_array in every loop.
I built a similar program for debug, where all seems to be good:
```go
package main
import (
"fmt"
"time"
)
func main() {
var a [32]int
go func() {
time.Sleep(1 * time.Second)
fmt.Println("goroutine:", a)
}()
a[1] = 4
{
a[2] = 6
}
fmt.Println("main:", a)
time.Sleep(5*time.Second)
}
```
