Javascript result in date_modify twig

Question

How to insert the result:

<script>
var date = new Date();
document.write(date.getTimezoneOffset());
</script>

in

{{ post.published_at|date_modify("+999 mins")|date("m/d/Y") }}

paste instead of 999.

Does this answer your question? [What is the difference between client-side and server-side programming?](https://stackoverflow.com/questions/13840429/what-is-the-difference-between-client-side-and-server-side-programming) — DarkBee, Jul 29 '20 at 10:04

Is this solution safe (correct)?

Passed the value in cookie:

<script>
    var now = (new Date().getTimezoneOffset()*-1);
    document.cookie = "timezoneoffset="+now;
</script>

Took it to {{ var }}:

     function onStart()  { 
                    if(isset($_COOKIE["timezoneoffset"])) {
                            $time = $_COOKIE["timezoneoffset"];
                            }
                            else {
                            $time = 0;
                            }
                    $this['var'] = $time;
                }

Ajax updated the partial:

{{ post.published_at|date_modify("+" ~ var ~ "mins")|date("m/d/Y") }}
