From what you describe, neither call looks declined. A declined call usually goes to voicemail after one ring or sooner, and both of yours rang for about the same time.
The 8 and the 2 seconds don't count the ringing. The call log counts the time a call was connected, and a call counts as connected once voicemail answers it. So both numbers are time spent connected to voicemail before the call ended. I can't tell from here why one ran 6 seconds longer, but that isn't a sign of a decline.
One thing the log can't show: if someone lets it ring the whole time and then presses decline, your log looks the same as for a call nobody touched.
