Always getting 20:mm when using tempus dominus datetimepicker

Question

I am using tempus dominus datetimepicker. I create record in db using create page where I set start time e.g. 15:30, in database everything is saved as normal, but when I want to edit the record using edit page I always get 20:30 in field for Time. I am using .NET Core 3.1.

$('#timepicker').datetimepicker({
  format: 'HH:mm',
  locale: 'mk',
});

<div class="form-group col-3">
 <label asp-for="Time" class="control-label">@DbResHtml.T("Време","Resources")</label>
 <div class="input-group date" id="timepicker" data-target-input="nearest">
  <input asp-for="Time" required type="text" class="form-control datetimepicker-input" data-target="#timepicker" />
   <div class="input-group-append" data-target="#timepicker" data-toggle="datetimepicker">
     <div class="input-group-text"><i class="fa fa-clock"></i></div>
   </div>
 </div>
<span asp-validation-for="Time" class="text-danger"></span>
</div>

What should I change here, I have tried changing value dynamically using jquery but that attemp was unsuccessful.
