title: How to convert text time to datetime in js
body: <p>I have some string time like "32 mins ago" or "Today 09:51", "y-day 02:25".</p>
  
  <p>How could I translate this into unix timestamp? I know it is not as precise but for database sorting it will do the job.</p>
  
  <p>I found multiple libraries to make those strings but none seems to be able to revert back.</p>
