One-dimensional model for study of sub--femtosecond experiment with metal surface is put forward. The important features of the system, such as the pseudopotential for electron motion in the metal bulk, abrupt decrease of the normal to the surface external electromagnetic field in the bulk, finite value of the mean free path for electrons in the metal, and action on the ejected electron by the (stationary) screened positive hole in the metal are included in the model. The results obtained reveal dependence of the streaking effect on the final energy of the ejected electron. Meanwhile, the dependence of the streaking on the character of the initial state (localized or delocalized) appears to be more pronounced. This result may provide an additional mechanism for interpretation of the results of very recent experiment [Cavalieri \emph{et.al}, NATURE \textbf{449} 1029-1032 2007 ].
