14,400 Seconds
That was my viva. It sounds a lot, but it’s only four hours. Tick-tick-tick times 4800 and I was done!
I’ve met a handful of people with similar or longer vivas. Sometimes the viva is long, or can feel long, but often they just fly by no matter what the clock says.
And really: they don’t compare to the 20-something million seconds you’ve invested in your PhD.
