Does any one knows how to include the time variable?

Hello, one of the euler's is,

\partial_{c}U(c_{t})=\frac{beta(t+1)}{\beta(t)}\partial_{c}U(c_{t+1})(1-\partial_{k}f(k_{t+1})-\delta)

where,

\beta(t) is a function that depends on time (not \beta^{t}), but I don't know how to included in the model using Dynare's syntax. Suggestions are welcome.

Could you explain the intuition of what you are trying to do? If beta is really depending on the time point t, you model is not stationary and Dynare won't solve it.
