Query: Ioffe Time in Double Logarithmic Approximation   We analyze the light cone (Ioffe) time structure of the gluon distribution
function in the double logarithmic approximation. We show that due to QCD
evolution Ioffe equation is modified. The characteristic light cone time of the
gluons does not increase as fast with increasing energy (decreasing Bjorken x)
as predicted by the parton distributions exhibiting Bjorken scaling due to the
increase of the transverse momenta of the gluons in the DGLAP ladder.
