Pulse Monitoring scheme

I am trying to design a scheme to monitor 4 sets of pulses from relays. When a pulse comes in I want to time stamp the pulse to millisecond accuracy and send the information (time of pulse) to a PC in a comma separated file. Below is the format I want.

Relay 1 Relay 2 Relay 3 Relay 4
14:21.102 14:21.101 14:21.102 14:21.100
14:21.106 14:21.105 14:21.103 14:21.101
14:21.107 14:21.106 14:21.104 14:21.103


What will be the best PIC for this kind of application. Your contributions, gurus out there, will be highly appreciated.

Can you give us a circuit dia,your going to be limited by the speed of the relays operating, can you not have an extra set of contacts on each relay voltage free? Then you could use the contacts directly on the pic..
