I'm trying to understand why as.Date() is converting a the modified date of
a file from August 22 to August 23.
> foo <- file.info(file.to.process)
> str(foo)
'data.frame': 1 obs. of 10 variables:
$ size : num 5.37e+09
$ isdir : logi FALSE
$ mode :Class 'octmode' int 436
$ mtime : POSIXct, format: "2010-08-22 23:14:52"
$ ctime : POSIXct, format: "2010-09-13 11:34:31"
$ atime : POSIXct, format: "2010-09-09 15:42:00"
$ uid : int 503
$ gid : int 503
$ uname : chr "ayee"
$ grname: chr "ayee"
> as.Date(foo$mtime)
[1] "2010-08-23"
In this case as.Date(foo$mtime) gives August 23. I would have expected
August 22.
Thanks,
Andrew
