Is
crazylookingtimes <- c(993340800.00, 993254400.00, 994809600.00)
class(crazylookingtimes) <- "POSIXct"
[1] "2001-06-24 01:00:00 BST" "2001-06-23 01:00:00 BST"
[3] "2001-07-11 01:00:00 BST"
what you wanted (probably not in that time zone)? Or
format(crazylookingtimes, "%y%d%m%H%M%S")
[1] "012406010000" "012306010000" "011107010000"
if you really want an illogical format like YYDDMMHHMMSS ....
See our article in the latest Rnews for more background details.
It would be pretty unusula to have raw Unix times.
