Why is the time string returned by the cnosdb query different from the RFC3339 format of golang?

Question

golang code：

func main() {
    fmt.Println(time.Now().Format(time.RFC3339))
    fmt.Println(time.Now().UTC().Format(time.RFC3339))
}

golang output：

2023-09-01T10:56:32+08:00
2023-09-01T02:56:32Z

cnosdb query result：

| cnosdb         | telegrafbfr   | 2023-09-01T02:15:00 | 0        | 1000    |

Does cnosdb have any considerations for this implementation?
