May 8, 2012 at 18:30 comment added kassandra Misha, that argument sounds plausible to me. Thank you very much!
May 8, 2012 at 17:13 comment added Misha Look at a small coordinate neighborhood $U$ on $M$, then $g_{ij}(x,t)$ is assumed to be a smooth matrix-valued function on $U\times [0,T)$, where $x\in U, t\in [0,T)$ and smoothness at $0$ as usual means that you can extend $g_{ij}(x,t)$ to a smooth function on $U\times (-\epsilon,T)$, for some $\epsilon>0$.
