Try this:
library(chron)
x <- "2005-12-05T00:00:00+02:00"
datetime <- chron(as.Date(x), substring(x, 12, 19))
sgn <- switch(substring(x, 20, 20), "+" = +1, "-" = -1)
offset <- as.numeric(times(paste(substring(x, 21), "00", sep = ":")))
datetime + sgn * offset
# or perhaps the last line should be:
datetime - sgn * offset
