The default ntp client since Fedora 16 is chrony, the chronyd service.  a `journalctl -b|grep ntp ` would probably match some chrony activity, and once you learn from that or documentation what the service is actually called, you can do `journalctl -u chronyd -otherfilters`.
Also, just like with less or vim, you can press '/' in parsed log output then type a string to search for.

No, the journalctl man page does not tell you about ntp logs, nor do the rsyslog pages explain grep :)
