Particulary I wish to realize a "PIC" based LED clock to display hour min sec and use the 10 MHz reference to arrange an  1/10 and 1/100 sec disaply.  Can anyone help me in finding schemes or any more flexible idea?

I am, at the moment, developing a led clock with an Arduino board that synchronizes its clock with the use of a NTP GPS server in my LAN. The clock can be configured through telnet and it syncs with the NTP server every 8 seconds. 

I expect to have it ready next week. 

I can send you the schematic if you so desire. 

Cheers,
Miguel
