I love using timers but I find myself wanting to use a stopwatch 
isn’t the whole point of WTH to make life easier?
I can’t speak to the ‘official’ reason for WTH from an HA standpoint.
But, what I see in the blog is:
What I am seeing from the WTH posts is that people that are unwilling to search (both previous posts and other WTH posts) post their questions and just expect it to happen.
I am sure I’ll get flagged for this. But, reality bites!!!
