Thanks for the clarification. Running ntpd like before (-p 
bad.example.org -p ntp.uio.no), LEDE master with Busybox 1.27.2 does 
seem to work:

root at LEDE:~# ntpdate -q ::1
server ::1, stratum 3, offset 0.000028, delay 0.02777
23 Aug 19:12:55 ntpdate[5416]: adjust time server ::1 offset 0.000028 sec
root at LEDE:~# echo $?
0

I also tested against my OpenWrt 15.05 VM and the current LEDE x86_64 
snapshot (r4723), and they both give the expected output as you describe 
(OpenWrt similar to above, LEDE fails).

Note that my patch in Patchwork only updates to Busybox 1.27.1, I will 
send the 1.27.2 patch shortly, after rebasing and testing it.
