\title{Truncate times Objects}
\description{
Truncate times objects.
}
\usage{
\method{trunc}{times}(x, units = "days", eps = 1e-10, \dots)
}
\arguments{
\item{x}{a \code{"times"} object.}
\item{units}{Can be one of \code{"days"}, \code{"hours"},
\code{"minutes"}, \code{"seconds"} or an unambiguous abbreviated
version of any of those.}
\item{eps}{Comparison tolerance. Times are considered equal if their
absolute difference is less than \code{eps}.}
\item{\dots}{further arguments to be passed to or from methods.}
}
\details{
The time is truncated to the second, minute, hour or day or to the
value specified.
There is also a \code{round} method which has the same arguments as
the \code{trunc} method, and performs rounding instead of truncation.
}
\value{
An object of class \code{"times"}.
}
\seealso{
\code{\link{trunc}} for the generic function and default methods.
}
\examples{
tt <- times(c("12:13:14", "15:46:17"))
trunc(tt, "minutes")
trunc(tt, "min")
trunc(tt, times("00:01:00"))
trunc(tt, "00:01:00")
trunc(tt, 1/(24*60))
tt2 <- structure(c(3.0, 3.1, 3.5, 3.9), class = "times")
trunc(tt2, "day")
trunc(tt2)
