 2. Any integer numeric type (such as INT and BIGINT). In this case, the data will be considered as epoch time of `1970-01-01 00:00:00`. 
-You should set precision of the value (default is 0). Currently, There are four valid precisions: `0` (for epoch seconds), 
-`3` (for epoch milliseconds), `6`(for epoch microseconds) and `9` (for epoch nanoseconds).

 3. STRING. In this case, if you didn't set the time unit, the data will be considered as formatted string of DATE, 
 DATETIME or TIMESTAMP value. Otherwise, the data will be considered as string value of epoch time. So you must set time 
 unit in the latter case.

 `date_format` is a flexible function which is able to convert the temporal value to various formats with different format 
 strings. A most common format string is `yyyy-MM-dd HH:mm:ss.SSS`. Another example is `yyyy-ww` which can extract the year 
 and the week-of-the-year from the input. Note that the output is affected by the locale. For example, in some regions the 
 first day of a week is Monday while in others is Sunday, so if you use `date_format(date_col, yyyy-ww)` and the input of 
-date_col is 2024/01/07 (Sunday), the output maybe `2024-01` (if the first day of a week is Monday) or `2024-02` (if the 
+date_col is 2024-01-07 (Sunday), the output maybe `2024-01` (if the first day of a week is Monday) or `2024-02` (if the 
 first day of a week is Sunday).
