Google 计算引擎时区

Question

我想知道为什么我位于 us-central1-a 区域的 google 计算引擎虚拟机 (Red Hat Enterprise Linux 7) 使用格林威治时区。 NTP 服务器不工作？

Answer 1

查看文档 CHAPTER 3. CONFIGURING THE DATE AND TIME:

By default, the system is configured to use UTC.

Coordinated Universal Time (or UTC) is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude, and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT).

我在 us-central1-a 创建了测试虚拟机并检查了时间和 NTP status:

$ timedatectl 
      Local time: Mon 2020-05-11 08:50:18 UTC
  Universal time: Mon 2020-05-11 08:50:18 UTC
        RTC time: Mon 2020-05-11 08:50:18
       Time zone: UTC (UTC, +0000)
     NTP enabled: yes
NTP synchronized: yes
 RTC in local TZ: no
      DST active: n/a

$ ntpstat
synchronised to NTP server (169.254.169.254) at stratum 3
   time correct to within 1 ms
   polling server every 64 s

一切看起来都像预期的那样。此外，我检查了其他区域的虚拟机并发现了相同的默认设置。

您可以按照说明更改时区 3.1.4. Changing the Time Zone:

To list all available time zones, type the following at a shell prompt:
timedatectl list-timezones
To change the currently used time zone, type as root:
timedatectl set-timezone time_zone
Replace time_zone with any of the values listed by the timedatectl list-timezones command.
