One of the frontiers of modern electron scattering instrumentation is\nimproving temporal resolution in order to enable the observation of dynamical\nphenomena at their fundamental time-scales. We analyze how a radiofrequency\ncavity can be used as an electron longitudinal lens in order to produce a\nhighly magnified temporal replica of an ultrafast process, and, in combination\nwith a deflecting cavity, enable streaked electron images of optical-frequency\nphenomena. We present start-to-end simulations of an MeV electron beamline for\ntwo variations of this idea (a `magnifying-glass' and a `point-projection'\nconfiguration) showing the feasibility for an electron probe to achieve single\nshot 1.4 fs(rms) temporal resolution.\n
