Your example works for me:

> library(zoo)

Attaching package: 'zoo'

        The following object(s) are masked from package:base :
         as.Date.numeric 


> 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
