Wrong result on contact search api by timestamp

I am using v3 and want to get all the contacts created in 24hrs

$search_filter = [ "filter_groups" => [ [ "filters" => [ [ "propertyName" => "createdate", "operator" => "lt", "value" => today()->timezone('UTC')->subDay()->timestamp * 1000, ] ] ] ], 'properties' => $properties, 'limit' =>100, "after" => $after ];

but Hubspot returning me the all contacts instead of newly created records in given timeframe

Hi, @IntegriPro :waving_hand: Thanks for reaching out. You are using the Search API, correct?

Hey, @stefen @miljkovicmisa, do you have any suggestions for @IntegriPro on setting up the Search API filters in the manner they are wanting?

Best,
