Thanks a lot. But i have one more doubt one of the attribute i have is time of edge formation
id1,id2,label,time 51,66,0,315522000 51,66,0,315522000 140,157,0,315522000 140,173,0,415522000 so is there any attribute for storing timestamps like for weight or color or if i store it in color would i lose the information?
