Here is what I do:
R> library(fBasics)
R> ts<-dummyDailySeries(x = rnorm(365), units = NULL, zone = "",
FinCenter ="")
R> class(ts)
[1] "timeSeries"
attr(,"package")
[1] "timeSeries"
R> (s <- as.character(time(ts)[1]))
[1] "1970-01-01"
R> class(s)
[1] "character"

I added a reproducible example to my question...
ts<-dummyDailySeries(x = rnorm(365), units = NULL, zone = "", FinCenter =
"")
(ts[1,0]) #returns first date in return series
GMT
1970-01-01
ttt<-(sprintf("%s",ts[1,0]))
print(ttt)
character(0)
ttt<-(ts[1,0])
print(ttt)
GMT
1970-01-01
what I want to get is a string containing "1970-01-01"
Thank you.

I have a timeseries object, ts, and want to get the first date in the
series into a string so I can concatenate it with a SQL query. Input and
output are shown below. I must be missing something very basic, but I
can't seem to pry the data ("2008-07-01") into a string variable. Any
suggestions would be appreciated.
Thank you,
Andrew
