Try this:
DF <- data.frame(tt = ISOdate(2009, 1:12, 1), x = 1:12, y = 1:12)
st <- as.POSIXct("2009-05-01 00:00:00")
en <- as.POSIXct("2009-07-01 23:59:59")
DF[DF$tt > st & DF$tt < en, ]
If the data in DF is numeric you would probably be better off
using a zoo series than a data.frame in which case you can
use window.zoo:
library(zoo)
z <- read.zoo(DF, tz = "")
z0 <- window(z, st = st, end = en)
plot(z0)
See the three vignettes in the zoo package, ?read.zoo and ?window.zoo
