What's hard to understand? before any NTP server can serve clients.. it first must be totally synchronized with another time source, whether that's a remote server or a local timedelta sensor.. it doesn't mater.
This is the kind of daemon that you simply ignore.. the time will be updated incrementally.
You can use
rdate(8) with the -n argument (..SNTP protocol) for immediate updates.. but if you're losing a lot of time, then it seems likely that the clock battery is dying and you'll need to replace it.
