Dear Sir, I have been working with R for some time now and I am very happy with it, but I have found a problem that I could not resolve. Could you please give me some hint about how to transform POSIX time data in seconds to string format?. (eg. 995752800 -> year-month,day,hour,min, sec) I tryed with Sys.time(), strptime() and date() but without success.
Is that the number of seconds since 1970-01-01?
x <- 995752800
class(x) <- c("POSIXt", "POSIXct")
x
[1] "2001-07-21 23:00:00 GMT Daylight Time" in my locale. Use format on `x' to get the format you want. (This is deliberately not made easy by as.POSIXct, as there is no way to check the numbers are indeed POSIX times.)
