在clojure中将unix时间戳转换为人类可读的日期和时间

数据库查询返回unix时间戳中的日期和时间。我试图使用clojure将其转换为人类可读的时间，然后将日期和时间拆分为日期和时间下的两列

看一看

例如，下面是如何将（长）时间戳转换为日期时间：

user=> (clj-time.coerce/from-long 893362442345)
#<DateTime 1998-04-23T20:14:02.345Z>

根据需要格式化结果的方式，您可以从许多不同的内置格式化程序中进行选择：

user=> (show-formatters)

或者创建一个自定义的：

(def custom-formatter (formatter "yyyyMMdd"))

---

我发现缺少名称空间令人困惑。例如，

（from long）

实际上是

（clj time.concure/from long）

。

(def custom-formatter (formatter "yyyyMMdd"))
