NTP access restriction

Hi Experts,

Any ideas why a random NTP server from the Internet can access to my router via NTP although there is an access-list configured?  Thanks

R1#show run | s ntp

ntp access-group query-only 1

ntp server X.X.X.X

R1#show access-lists 1

Standard IP access list 1

    10 permit X.X.X.X

Output of NTP server at <router IP>

ntpdate

30 Jan 07:16:40 ntpdate[8285]: ntpdate 4.2.6p5@1.2349-o Mon May 20 14:24:36 UTC 2013 (1)
server <router ip>, stratum 0, offset 0.000000, delay 0.00000
