Maybe change this:
ntp server 10.254.101.200

to:
ntp server 10.254.101.200 prefer


Also let us know what the below command gives you.
show ntp status


And if you needed to set your time you can always choose to manually enter it:

Switch# clock set 17:32:00 26 October 2013

The NTP server command will tell the switch what NTP source to sync with.  It will not allow the device to act as a NTP server itself.

To configure an IOS device to function as a NTP source, use the ntp master command.

ntp master <stratum number>

If you don't configure the stratum number it will use a high number such as 8 or 9 (instead of a lower value which means it's closer to an atomic clock source).
