I am really not sure why the time output looks so funky but here are some timings of the GraphicsMagick configure script using /bin/dash and /bin/bash on an Ubuntu 18.04 LTS system. The timing difference is not as much as I remember from years ago. The difference might be due to configure script design improvements, Bash implementation improvements, and the fact that this is a much faster system.

/bin/dash
