Making update_until work on time steps of 3600 seconds. I actually think it was working fine on the one hour time steps, but this is good.
Changes
Instead of making update_until work on a time unit of one hour, it works on a time unit of 3600 seconds. I think it was probably working just fine before. But, I added in the possibility for updating a fraction of the time step, which is an inappropriate use of this model, so there is also a warning.
