◆ getOffsetDate()

static MediaWiki\Pager\ReverseChronologicalPager::getOffsetDate	(	$year,
		$month,
		$day = -1 )

static

Core logic of determining the offset timestamp such that we can get all items with a timestamp up to the specified parameters.

Given parameters for a day up to which to get items, this function finds the timestamp of the day just after the end of the range for use in a database strict inequality filter.

This is separate from getDateCond so we can use this logic in other places, such as in RangeChronologicalPager, where this function is used to convert year/month/day filter options into a timestamp.

Parameters

int	$year	Year up to which we want revisions
int	$month	Month up to which we want revisions
int	$day	[optional] Day up to which we want revisions. Default is end of month.
