I´ve issued the "ntp server X.X.X.X" command on some switches and I observed that the "ntp clock-period" parameter has not been installed automatically on some of them and the ntp status shows "Clock is unsynchronized". All the switches has the same IOS version.
here's a test you can try. On an available router, issue (if your folks let you) the command "ntp master 1" to make it a stratum 1 clock. On the switch, point it's ntp to this stratum 1 clock. Remember - previously existing ntp settings _are not_ removed when you issue new commands, you have to manually "no" those.
If the switch syncs, the problem is elsewhere, or the ntp clock you specified earlier isn't responding or a firewall/proxy is blocking ntp. Remember to clean up and remove the stratum 1 clock when your testing is done.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
