TIME (the Tomographic Ionized-carbon Intensity Mapping Experiment) is a new instrument designed to probe the epoch of reionization (EoR) by measuring the 158 um ionized carbon emission line [CII] from redshift 5 - 9 using line intensity mapping.  I will describe the instrument which is an R of ~100 spectrometer sensitive to the 200-300 GHz radiation.  We will detect the [CII] clustering fluctuations from faint galaxies during EoR and compare these measurements to predicted [CII] amplitudes from current models. The [CII] intensity mapping measurements are complimentary to both 21-cm measurements of the EoR and direct detections of high redshift galaxies with HST, ALMA, and, in the future, JWST.
