Insert date information to my database

Moving on – because I have lost so much time over this and have to Rush – how do just put the current time into a hidden field and submit to a standard datetime mysql column value?

Wappler shows a whole lot of options but I see nothing that just shows , for instance, the SERVER Local time.

What would I put here, please?

<div class="form-group">
  <label for="inp_regtime">Zeit</label>
  <input type="date" class="form-control" id="inp_regtime" name="regtime" aria-describedby="inp_regtime_help" placeholder="Enter Regtime" dmx-on:input="">
</div>

Now looking at
