We propose a new technique to realize an optical time lens for ultrafast temporal processing that is based on four-wave mixing in a silicon nanowaveguide. The demonstrated time lens produces more than $100\pi$ of phase shift, which is not readily achievable using electro-optic phase modulators. Using this method we demonstrate $20\times$ magnification of a signal consisting of two $3\mathrm{ps}$ pulses, which allows for temporal measurements using a detector with a $20\mathrm{GHz}$ bandwidth. Our technique offers the capability of ultrafast temporal characterization and processing in a chip-scale device.
