fwrite with POSIX type

[yitang]

Hi, I am tyring the fwrite function. it reallllly fast! But it doesn't support POSIXct. Is it a bug?

library(data.table)
ds <- data.table(id=1:10, x=Sys.time())
fwrite(ds, "~/tmp.csv")
fread("~/tmp.csv")
file.remove("~/tmp.csv")

R> 
    id         x
 1:  1 1.464e+09
 2:  2 1.464e+09
 3:  3 1.464e+09
 4:  4 1.464e+09
 5:  5 1.464e+09
 6:  6 1.464e+09
 7:  7 1.464e+09
 8:  8 1.464e+09
 9:  9 1.464e+09
10: 10 1.464e+09

Not a bug, just not yet supported (what you're seeing is the integer representation of your column, see unclass(ds$x)).

This is covered by #1664.

Dup of #1664. We're aware of this. It's on the to-do list.
