Right now there's no way to enforce a specific value of now_ms upon startup in order to compensate for the time it takes to load a config, specifically when dealing with the health check startup. For this we'd need to force the now_offset value to compensate for the last known value of the current date. This patch exposes a function to do exactly this.
