We present results for QCD in the strong coupling limit, obtained from a worm-type algorithm on a discrete spatial lattice but with continuous Euclidean time. This is obtained by sending both the anisotropy parameter $\gamma^2=a/a_t$ and $N_\tau$ to infinity at fixed temperature $T=\gamma^2/N_\tau$. The gain is that no continuum extrapolation for $N_\tau \rightarrow \infty$ has to be carried out. We contrast these computations with those obtained on discrete lattices for large $N_\tau$. We discuss the determination of the critical temperature for U(3) (purely mesonic) in the chiral limit, and the extension to SU(3) (baryons included) with a baryon chemical potential. We finally discuss the possibility of a continuous time worm algorithm at finite quark mass.
