\title{
Generate Dates and Times Components from Input
}
\description{
Create objects which represent dates or times.
}
\usage{
dates(x, \dots)
times(x, \dots)
}
\arguments{
\item{x}{a chron object, a character vector, or a numeric vector
specifying time. If character, it must be in a format recognized by
\code{chron()}. If numeric, it specifies Julian dates, i.e., number
of days since an origin.}
\item{...}{parameters for \code{chron()}.}
}
\value{
An object of class \code{dates} or \code{times}, depending of the
function called.
These functions return objects inheriting from dates and times,
respectively. They call \code{chron()} if \code{x} does not belong to
any of the chronological classes.
}
\examples{
dts <- dates(c("02/27/92", "02/27/92", "01/14/92",
"02/28/92", "02/01/92"))
dts
# [1] 02/27/92 02/27/92 01/14/92 02/28/92 02/01/92
class(dts)
x <- chron(dates = c("02/27/92", "02/27/92", "01/14/92", "02/28/92"),
times = c("23:03:20", "22:29:56", "01:03:30", "18:21:03"))
dates(x)
# [1] 02/27/92 02/27/92 01/14/92 02/28/92
