Time-dependent measurements of the CKM angle $\gamma$ at LHCb

The startup of the LHC opens many new frontiers in precision flavour physics, in particular expanding the field of precision time-dependent CP violation measurements to the $B^0_s$ system. This contribution reviews the status of time-dependent measurements of the CKM angle $\gamma$ at the LHC's dedicated flavour physics experiment, LHCb. Particular attention is given to the measurement of $\gamma$ from the decay mode $B^0_s \to D^{\pm}_s K^{\mp}$, a theoretically clean and precise method which is unique to LHCb. The performance of the LHCb detector for this and related modes is reviewed in light of early data taking and found to be close to the nominal simulation performance, and the outlook for these measurements in 2011 is briefly touched on.
