It will be a way for players who hoard gold to finally dump it. This stimulates the in-game economy.
Overall I believe this will have a positive effect on the overall economy (which is already far too inflated). The only means of keeping inflation down is through gold sinks at vendors or the AH cut, and if these time cards can be sold on the AH, then you just added an extra gold sink.
