When should you use DateTime and when should you use Time?

Two obligatory links on what a strange thing &quot;time&quot; is:<p>[1]: <a href="http:&#x2F;&#x2F;infiniteundo.com&#x2F;post&#x2F;25326999628&#x2F;falsehoods-programmers-believe-about-time" rel="nofollow">http:&#x2F;&#x2F;infiniteundo.com&#x2F;post&#x2F;25326999628&#x2F;falsehoods-programm...</a><p>[2]: <a href="http:&#x2F;&#x2F;infiniteundo.com&#x2F;post&#x2F;25509354022&#x2F;more-falsehoods-programmers-believe-about-time" rel="nofollow">http:&#x2F;&#x2F;infiniteundo.com&#x2F;post&#x2F;25509354022&#x2F;more-falsehoods-pro...</a>

This is superbly well explained with a great example but it doesn&#x27;t quite explain why I wouldn&#x27;t just use DateTime for everything? Or did I miss something?
