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?
