◆ getOffsetDate()

static 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 an 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$yearYear up to which we want revisions
int$monthMonth up to which we want revisions
int$day[optional] Day up to which we want revisions. Default is end of month.
Returns
MWTimestamp Timestamp or null if year and month are false/invalid
