-根据[这份 `YAML` 规范](https://yaml.org/type/timestamp.html)，符合 `ISO 8601` 标准的时间格式都会被解析为 `Date` 类型，且**不显式标注时区的时间戳都会作 UTC 处理**。
-
-但是为了方便写作与从其他框架迁移，我们将未显式标注时区的时间戳解析为**系统时区**对应的时间（即 `2024-07-06 12:00:00` 在 `Asia/Shanghai` 下会解析 为 `2024-07-06T12:00:00+08:00`）。
-
-无论如何，我们建议**显式**添加时区信息，例如：
-
-```yaml
-date: 2024-07-06 12:00:00 +8
-```
-
-如果你不喜欢显式标记，请**务必**在构建前指定系统时区：
-
-```bash
-sudo timedatectl set-timezone Asia/Shanghai
-```
-
-这样就能正确解析为 UTC+8 时区的 `2024-07-06 12:00:00`。
-
-主题作者也能通过在 `scaffolds/post.md` 中使用 `date: <%=date%> +8` 来实现这一点。

-According to [this `YAML` specification](https://yaml.org/type/timestamp.html), time formats that conform to the `ISO 8601` standard will be parsed as `Date` type, and **timestamps without explicitly marked time zones will be treated as UTC**.
-
-However, for the convenience of writing and migrating from other frameworks, we parse timestamps without explicitly marked timezones under system timezone (i.e., `2024-07-06 12:00:00` will be parsed as `2024-07-06T12:00:00+08:00` in `Asia/Shanghai`).
-
-If you don't like explicit marking, **be sure** to specify the system time zone before building:
-
-```bash
-sudo timedatectl set-timezone Asia/Shanghai
-```
-
-Nevertheless, we recommend **explicitly** adding time zone information, for example:
-
-```yaml
-date: 2024-07-06 12:00:00 +8
-```
-
-This way, it can be correctly parsed as `2024-07-06 12:00:00` in the UTC+8 time zone.
-
-Theme authors can also achieve this by using `date: <%=date%> +8` in `scaffolds/post.md`.
