You would have to clarify what you are hoping to accomplish. Do you just want to get the correct time of day/date down in the FPGA? Or do you want a local clock synchronized with some high degree of precision with the NTP server?

Ted, thanks for looking for clarification. In short, I'm trying to get some sort of high degree of precision with an NTP server. The easiest I'm thinking would be to use some method that already exists and send a host computer's NTP time over JTAG to the FPGA. Any thoughts are welcome.
To give better idea of what I'm trying to accomplish, I'm encrypting a stream of data over Ethernet and need to keep several Altera Boards in time sync. I'm trying to do it out-of-band, hence why I'm trying to stay away from uCLinux SSH/Telnet over Ethernet and am thinking JTAG would be the way to go. I'm aware that the Nios II has an internal clock that I can set, but I would need to send the initial NTP time and probably periodic updates to accommodate for any drift.
