Answer 1

Well.. You can just set the value by using the "value" attribute:

<input type="datetime-local" name="followupon" value="2014-01-02T11:42:13.510">

See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/datetime-local#Value for more information

If you want to use the current date, you can use php like so:

<input type="datetime-local" name="followupon" value=<?php echo date('Y-m-d\TH:i:s'); ?>">
