As -zinb- is objecting to the use of operators such as L. in the call, why not create those variables explicitly with -generate- beforehand? You can that manual, but you could probably do it in a loop.
But don't expect -zinb- to have any special knowledge of time series.

Stata won't allow lagged right-hand-side variables(time-series operators, which the -nbreg- command does allow) when I use the -zinb- command. Is there a way to solve this problem?
Or do I have to manually lag all the explanatory variables?
