Core_Date::span

Returns time difference between two timestamps, in human readable format. If the second timestamp is not given, the current time will be used. Also consider using [Date::fuzzy_span] when displaying a span.

$span = Date::span(60, 182, 'minutes,seconds'); // array('minutes' => 2, 'seconds' => 2) $span = Date::span(60, 182, 'minutes'); // 2

string Core_Date::span( integer $remote [, integer $local = null , string $output = string(45) "years,months,weeks,days,hours,minutes,seconds" ] )
