This is the output from show_delta using the 'base' option: show_delta -b "Calibrating" tim_hp_run1 

This shows all the timing data relative to the line starting with the string "Calibrating" (about 19 lines into the output). The "-b" option can be used to set a different time base for the timing information. From this you can easily tell that calibrate_delay_loop took 268 milliseconds, or more than a quarter of a second.

Compare this output to PrintkTimesSample1 or PrintkTimesSample2
