Datetime tag on delayed chapters

[len]

How about adding datetime tags on delayed chapter warning so code instead:

<div class="alert alert-danger text-center" role="alert"><strong><span class="fas fa-exclamation-circle fa-fw" aria-hidden="true" title="Warning"></span> Warning:</strong> Due to the group's delay policy, this chapter will be available in 11 hours.</div>

would become

<div class="alert alert-danger text-center" role="alert"><strong><span class="fas fa-exclamation-circle fa-fw" aria-hidden="true" title="Warning"></span> Warning:</strong> Due to the group's delay policy, this chapter will be available in <time datetime="2018-06-10 02:21:29 UTC">in 11 hours</time>.</div>

This could be helpful for local js scripts

Cheers
