How to set limits on the highloadblock multilevel filter?

Question

1C-Bitrix

There is an HL block, one of the timestamp fields, the second multiple id of related elements from another table.
You need to get records:
- 1 record for each id of the associated element, the timestamp of which is the largest, but less than the current
one - all records for each id of the associated element, the timestamp of which is greater than the current
The filter itself is simple, but I can’t figure out how to set the limits:

$rsData = $entity_data_class::getList(array(
    "order" => array("UF_TIMESTAMP" => "DESC"),
    "filter" => array(
        'LOGIC' => 'OR',
        array(
            "UF_IDS" => $IDs,
            "<=UF_TIMESTAMP" => $currentTS
        ),
        array(
            "UF_IDS" => $IDs,
            ">=UF_TIMESTAMP" => $currentTS
        )
    )
));
