time series - cbind

Hi,
I have a time series ts.score that gets created based on a function.
When I print the time series out it prints two rows, first the date
then the value.

2011-06-14
-1.25947868

The function gets called multiple times in my script and I'm trying to
append the time series to an object called ts.bind using the cbind
function like so. The only problem I have is that the date is an index
for all of the columns, which is only correct for the first column. Is
there a way that I can associate the correct dates with each column?

ts.bind <- cbind(ts.bind, ts.score)

                       ts.score          ts.score          ts.score
   ts.score        ts.score
2010-10-14   1.06493449   0.96323675   1.13255734   -0.3060238

I appreciate any help.
