OK, so maybe the issue wasn't the presence of a certificate but just that the bureaucrats made little effort to make them accurate. I mean here in the US, creating one of those is one of the first things that happens in the hospital. I have my original with my newboard footprints on it. Maybe an attempt to remedy baby switches, people taking home the wrong one. I'd guess that when a woman gives birth in her hut or remote village, the time and date aren't dutifully recorded to make the eventual certificate dead accurate.
