grafana mysql 数据源时差8小时问题

grafana pod加时区：

    spec:
      containers:
        - env:
            - name: TZ
              value: Asia/Shanghai

grafana用户选cst时区：
Configuration - 》 preferences -》 Timezone ->

sql中时间字段用UNIX_TIMESTAMP处理下：

SELECT
  UNIX_TIMESTAMP(created_at) AS "time",
  today_ip_count AS "ip"
FROM baidu_report_infos
WHERE
  $__timeFilter(created_at) AND
  domain = "sre.ink"
ORDER BY created_at
