Need to make date and time Time Zone: (UTC +02:00 Cairo) with format dd/mm/yyyy for synchronization my desktop application.

<div class="container">
   <p id="date"></p>
   <p id="time"></p>
   <p id="text">(UTC +02:00 Cairo)</p>
</div>

* {
  box-sizing: border-box;
}

body {
  color: black;
  background-color: white;
  font-family: 'Share Tech Mono', monospace;
}

p {
  margin: 0 auto;
  padding: 0 auto;
}

.container {
  text-align: center;
  margin-top: 10em;
}

#time {
  letter-spacing: 0.05em;
  font-size: 80px;
  padding: 5px 0;
}

#date {
  letter-spacing: 0.1em;
  font-size: 24px;
}

can you explain this a bit?
Do you mean when you change the time on your machine?
And do you mean that you want the browser to return some other date and time?

i want to pin date and time to this timezone UTC +20:00 Cairo, when user change time on machine, need to make the sync from pin something not from the local machine

The only way I know how (sorry I am not experienced with this topic) is to get the date and time from a server that is already in the required time zone. (Because otherwise you only have the local time and date on the person’s client machine)
