Doesn't look like ntp is setup correctly or the NTP server is unreachable. Under the show ntp status it should show the ntp server as a reference if it's working correctly. Commands should look something like this:

clock timezone PACIFIC -8
clock summer-time SUMMER recurring 2 Sun Mar 3:00 1 Sun Nov 3:00

ntp update-calendar
ntp server 129.6.15.28
