[R] is.na() == TRUE for POSIXlt time / date of "2014-03-09 02:00:00"

[John McKown]

"I'm so confused!" Why does is.na() report TRUE for a POSIXlt date &
time of 2014-03-09 02:00:00 ?

> q
[1] "2014-03-09 02:00:00"
> is.na(q)
[1] TRUE
> as.POSIXct(q)
[1] NA
> dput(q)
structure(list(sec = 0, min = 0L, hour = 2, mday = 9L, mon = 2L,
    year = 114L, wday = 0L, yday = 67L, isdst = 0L, zone = "",
    gmtoff = NA_integer_), .Names = c("sec", "min", "hour", "mday",
"mon", "year", "wday", "yday", "isdst", "zone", "gmtoff"), class = c("POSIXlt",
"POSIXt"))
> str(q)
 POSIXlt[1:1], format: "2014-03-09 02:00:00"
