How to remove empty values?

Answer 1

You need to check for empty value in $arFields['PROPERTY_TIME_VALUE']. If empty, then continue .
A better option is to add a check for a non-empty value to $arFilter. Alternatively '!TIME' => false

Answer 2

echo (!empty($arFields[PROPERTY_TIME_VALUE]))?$arFields[PROPERTY_TIME_VALUE].", ":"";

Answer 3

For starters: writing everything in one line is not the best manner.
2: PROPERTY_TIME_VALUE it is desirable to wrap "PROPERTY_TIME_VALUE" in quotes, of course, if it is not a constant
3: Add a check for the value

$arSelect = Array("ID","PROPERTY_TIME");
$arFilter = Array("IBLOCK_ID"=>34);
$res = CIBlockElement::GetList(Array(), $arFilter, false, Array("nPageSize"=>550), $arSelect);

while($ob = $res->GetNextElement()){
    $arFields = $ob->GetFields();

    if( !empty($arFields["PROPERTY_TIME_VALUE"]) )
        echo ($arFields["PROPERTY_TIME_VALUE"]).", ";

    // или:
    // if( empty($arFields["PROPERTY_TIME_VALUE"]) ) continue;
    // echo ($arFields["PROPERTY_TIME_VALUE"]).", ";
}
