### Timezone of date
|
||||
|
||||
In order to accurately record the release date of a post, you should not only setup the `timezone` of `_config.yml` but also provide the the post's timezone in field `date` of its Front Matter block. Format: `+/-TTTT`, e.g. `+0800`.

### Categories and Tags
|
||||
|
||||
The `categories` of each post is designed to contain up to two elements, and the number of elements in `tags` can be zero to infinity.

With the increasing number of posts, the number of categories and tags will increase several times! If we still manually create these *category*/*tag* type files, it will obviously be a super time-consuming job, and it is very likely to miss some of them(i.e. when you click on the missing `category` or `tag` link from a post or somewhere, it will complain to you '404'). The good news is that we got a lovely script tool `_scripts/py/pages_generator.py` to finish the boring task. Basically we will use it via `tools/init.sh` instead of running it separately. Check out its use case [here]({{ "/posts/getting-started/#option-1-built-by-github-pages" | relative_url }}).

- **Last modified date**
|
||||
## Last modified date
|
||||
|
||||
The last modified date of the posts is recorded as `seo.date_modified`, for example:
|
||||
The last modified date of a post is obtained according to its latest git commit date, and all the modified date of the posts should be stored in `_data/updates.yml`. For example:
|
||||
|
||||
```yaml
|
||||
---
|
||||
seo:
|
||||
date_modified: 2020-01-04 17:05:41 +0800
|
||||
---
|
||||
-
|
||||
filename: getting-started # the post filename without date and extension
|
||||
lastmod: 2020-04-13 00:38:56 +0800 # the post last modified date
|
||||
-
|
||||
...
|
||||
```
|
||||
|
||||
This date is equal to the lastest git-commit date of the post file and can be automatically generated by the tool script `_scripts/py/update_posts_lastmod.py`. Similar to the other script `pages_generator.py` mentioned above, it is also be called from `tools/init.sh`, so it doesn't have to be used separately.
|
||||
|
||||
You can choose to create this file manually, but as you may notice, the better approach is to let it be automatically generated by a tool script. And `_scripts/sh/dump_lastmod.py` was born for this! Similar to the another script `_scripts/sh/create_pages.sh` mentioned above, it is also be called from `tools/init.sh`, so it doesn't have to be used separately.
|
||||
|
||||
When some posts have been modified since their published date and also the file `_data/updates.yml` was created correctly, a list with the label **Recent Updates** will be displayed in the right panel of the desktop view, which records the five most recently modified articles.
