我查了GNU C 库手册，是通用 TZ 环境变量来设置的。在一台没有 systemd 的 arm 上测试 OK 。
但是普通的 X86 UBUNTU 用的是 /etc/localtime 配置文件 参考freedesktop 用 TZ 变量可以覆盖。
但明明 C 库只使用 TZ 环境变量，/etc/localtime 是如何生效的，是有个服务吗。

你看的这一篇文档标题叫 Specifying the Time Zone with TZ
应该思考一下，without 该怎么办呢 |

If the TZ environment variable does not have a value, the operation chooses a time zone by default. In the GNU C Library, the default time zone is like the specification ‘TZ=:/etc/localtime’ (or ‘TZ=:/usr/local/etc/localtime’, depending on how the GNU C Library was configured; see Installing the GNU C Library). Other C libraries use their own rule for choosing the default time zone, so there is little we can say about them.
TZ 空的时候就去读你说的路径了 |
