Edit /root/set-timezone.sh (around line 33), replace unconditional sleep 3 so it sleeps 1 hour, once it received a valid time via NTP:

    current_time=$(date)
    echo "当前时间: $current_time"

    # 延时5秒
#TM#    sleep 3
#TM-->
        if ! $synced ; then
          sleep 3
        else
          sleep 3600
        fi
#TM<--

        if ! $synced; then

Back to start
