* \brief C API: URelativeDateTimeFormatter, relative date formatting of unit + numeric offset.
|
|
*
|
|
* Provides simple formatting of relative dates, in two ways
|
|
* <ul>
|
|
* <li>relative dates with a quantity e.g "in 5 days"</li>
|
|
* <li>relative dates without a quantity e.g "next Tuesday"</li>
|
|
* </ul>
|
|
* <p>
|
|
* This does not provide compound formatting for multiple units,
|
|
* other than the ability to combine a time string with a relative date,
|
|
* as in "next Tuesday at 3:45 PM". It also does not provide support
|
|
* for determining which unit to use, such as deciding between "in 7 days"
|
|
* and "in 1 week".
