G.M.T.

is it me? or do ppl from pk have no sense of G.M.T. ?
take my reletives in the U.S.A sometimes they will call 1.30 because they are 5 hours backward ! (Amercians are backwards full stop) then the ppl in Pk. will phone like the same time as well, what is wrong with ppl? why you ppl in Pakistan have to do this to us Uk desi's ?
