/**
|
|
* Returns either a relative date or a formatted date depending

|
* on the difference between the current time and given datetime.
|
|
* $datetime should be in a <i>strtotime</i> - parsable format, like MySQL's datetime datatype.
|
|
*
|
|
* ### Options:
|
|
*
|
|
* - `format` => a fall back format if the relative time is longer than the duration specified by end
|
|
* - `end` => The end of relative time telling
|
|
* - `userOffset` => Users offset from GMT (in hours)
|
|
*
|
|
* Relative dates look something like this:
|
|
* 3 weeks, 4 days ago
|
|
* 15 seconds ago
|
|
*
|
|
* Default date formatting is d/m/yy e.g: on 18/2/09
|
|
*
|
|
* The returned string includes 'ago' or 'on' and assumes you'll properly add a word
|
|
* like 'Posted ' before the function output.
|
|
*
|
|
* @param string $dateTime Datetime string or Unix timestamp
|
|
* @param array $options Default format if timestamp is used in $dateString
|
|
* @return string Relative time string.
