@Rakesh Jesadiya Thanks for responding..
Sure. I'm updating my code here.
InstallData.php

 $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]); $eavSetup->removeAttribute(\Magento\Catalog\Model\Product::ENTITY, 'course_start_datetime');
 $eavSetup->addAttribute(       \Magento\Catalog\Model\Product::ENTITY,
        'course_start',
        [
            'group' => 'Custom Attribute',
            'label' => 'Enable Start Date',
            'type' => 'datetime',
            'input' => 'date',
            'input_renderer' => 'Velanapps\Test\Block\Adminhtml\Form\Element\Datetime',
            'class' => 'validate-date',
            'backend' => 'Magento\Catalog\Model\Attribute\Backend\Startdate',
            'required' => false,
            'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
            'visible' => true,
            'required' => false,
            'user_defined' => true,
            'default' => '',
            'searchable' => true,
            'filterable' => true,
            'filterable_in_search' => true,
            'visible_in_advanced_search' => true,
            'comparable' => false,
            'visible_on_front' => false,
            'used_in_product_listing' => true,
            'unique' => false
        ]
    );

And the block for input renderer is below:

 <?php
  namespace Velanapps\Test\Block\Adminhtml\Form\Element;
  use Magento\Framework\Data\Form\Element\Date;

  class DateTime extends Date {
       public function getElementHtml() {
           $this->setDateFormat($this->localeDate->getDateFormat(\IntlDateFormatter::SHORT));
           $this->setTimeFormat($this->localeDate->getTimeFormat(\IntlDateFormatter::SHORT));
           return parent::getElementHtml();
       }
  }
