docs: Date-time format that depends on the locale.
  
  The date-time pattern shows how to combine separate patterns for date (represented by {1})
  and time (represented by {0}) into a single pattern. It usually doesn't need to be changed.
  What you want to pay attention to are:
  - possibly removing a space for languages that don't use it, such as many East Asian languages
  - possibly adding a comma, other punctuation, or a combining word
  
  For example:
  - English uses `{1} 'at' {0}` or `{1}, {0}` (depending on date style), while Japanese uses
  `{1}{0}`.
  - An English formatted date-time using the combining pattern `{1}, {0}` could be
  `Dec 10, 2010, 3:59:49 PM`. Notice the comma and space between the date portion and the time
  portion.
  
  There are four formats (`full`, `long`, `medium`, `short`); the determination of which to use
  is normally based on the date style. For example, if the date has a full month and weekday
  name, the full combining pattern will be used to combine that with a time. If the date has
  numeric month, the short version of the combining pattern will be used to combine that with a
  time. English uses `{1} 'at' {0}` for full and long styles, and `{1}, {0}` for medium and short
  styles.
