Your example works for me:

> library(zoo)
Attaching package: 'zoo'
        The following object(s) are masked from package:base :

> foo<-zoo(1,order.by=as.Date("2007-10-09")) 
> bar<-zoo(2,order.by=as.Date("2007-10-10")) 
> bar <- rbind(zoo(0, order.by = index(foo)[1]), bar) 
> bar
2007-10-09 2007-10-10 
         0          2
