What does that time mean?

I tried searching Wikipedia for E and maths but found the e mathematical constant. My guess is E stand for Exponential and -5 is the power it is raised to. And the displayed time is a really small number. But that doesn’t make sense when compared to the other time in the question. 0.00013899803161621 is bigger than 9.0122222900391E-5.

If it means x times 105, then 9.0122222900391E-5 will be 0.000090122222900391 which is smaller than 0.00013899803161621. What does E stand for?
