During my brief brush with Arch a few years back I found their documentation to be extremely well-done. Given that, I find it odd I have never stuck with that distribution for long... Especially since I end up back at the Arch wiki for configuration advice over and over again. This time I could not remember the different options I used for NTPd configuration, and ended up back at the Arch Linux NTP article and the NTP pool web site.
Now it is saved here for safe-keeping, and I (hopefully) will not forget again. ;)
