Hello, What is the best way to concatenate POSIXct objects keeping the time zone attribute in a program? For example:
R> xx <- as.POSIXct(strptime(c("2006-09-26 12:00:00", "2006-09-26 13:00:00"), + format="%Y-%m-%d %H:%M:%S"), tz="GMT") R> xx [1] "2006-09-26 12:00:00 GMT" "2006-09-26 13:00:00 GMT" but, as ?c.POSIXct explains: R> c(xx, xx[1] - 60, xx[2] + 60) [1] "2006-09-26 07:00:00 CDT" "2006-09-26 08:00:00 CDT" [3] "2006-09-26 06:59:00 CDT" "2006-09-26 08:01:00 CDT" Is there something better/safer than simply setting the "tzone" attribute of the new object?
