Example(chron) doesn't work

Hi, there,

I have a similar problem. The chron example gives NA. dates doesn't work but
times does.

I would appreciate it if there's a fix for it.

Thanks,
Helena

example(chron)

chron> dts <- dates(c("02/27/92", "02/27/92", "01/14/92",
chron+                "02/28/92", "02/01/92"))

chron> dts
[1] <NA> <NA> <NA> <NA> <NA>

chron> # [1] 02/27/92 02/27/92 01/14/92 02/28/92 02/01/92
chron> tms <- times(c("23:03:20", "22:29:56", "01:03:30",
chron+                "18:21:03", "16:56:26"))

chron> tms
[1] 23:03:20 22:29:56 01:03:30 18:21:03 16:56:26
