In order to do what you want, you are going to need to have two separate always blocks, one for each edge of the clock, and then figure out a way to combine the outputs of the. In Verilog, this is described by the "always @ (posedge clk)" statement - if a reg gets assigned a new "state" one per rising edge of clk, then its behaviour is that of a flip-flop, and a synthesis tool will replace it with the equivalent flip-flop. The difference is that in the edge sensitive path, the source edge transition is used. I need a timestamp of start of some event and the end of the same. 1 The Circuits Required.
