/* Format a nice representation of 'time' relative to the current time.
|
|
*
|
|
* Examples include:
|
|
*
|
|
* 5 mins. ago (For times less than 60 minutes ago)
|
|
* Today 12:30 (For times >60 minutes but still today)
|
|
* Yest. 12:30
|
|
* Mon. 12:30 (Before yesterday but fewer than 7 days ago)
|
|
* October 12 (Between 7 and 180 days ago (about 6 months))
|
|
* 2008-06-30 (More than 180 days ago)
|
|
*
|
|
* The returned string is either static data (a string literal) or
|
|
* newly talloced data belonging to 'ctx'. That is, the caller should
|
|
* not modify nor free the returned value. But when the caller
|
|
* arranges for 'ctx' to be talloc_freed, then memory allocated here
|
|
* (if any) will be reclaimed.
