XF 1.5 Change Date from Default to Hours Ago

[Wesker]

How do you change the default date so it says something like

Latest: preg_replace(): No ending delimiter '#' found">Importing from SMF => preg_replace(): No ending delimiter '#' foundMystinen Metsätyömies, Today at 11:56 AM

Latest: preg_replace(): No ending delimiter '#' found">Importing from SMF => preg_replace(): No ending delimiter '#' foundMystinen Metsätyömies, 9 Hours Ago

Latest: preg_replace(): No ending delimiter '#' found">Importing from SMF => preg_replace(): No ending delimiter '#' foundMystinen Metsätyömies, 2 Days Ago

Latest: preg_replace(): No ending delimiter '#' found">Importing from SMF => preg_replace(): No ending delimiter '#' foundMystinen Metsätyömies, One Week Ago

Something like that?
