我正在试图将系统的日期和时间输出到文本文件。 当我这样做时, 时区会消失。 例如:
> Sys.time()
[1] "2012-05-24 09:58:38 CDT"
> currentTime <- Sys.time()
> currentTime
[1] "2012-05-24 09:58:49 CDT"
> cat(as.character(currentTime), sep = "
")
2012-05-24 09:58:49
时区怎么了,我怎么拿回来?

试试这个代替:
cat(format(Sys.time(),usetz = TRUE))
POSIXct 对象的打印方法调用format
,使用 usetz = TRUE
,这就是为什么你在控制台看到时区的原因(打印方法在幕后被调用)。
