Now that the client sources are alone here in their own directory, (with all the library sources down inside the lib directory), we can break the client up into multiple files without mixing the files up. The hope is that these smaller files will be easier to manage and maintain.

/* 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.
