Just to be complete: in addition to "its" in package its "timeSeries" in fBasics which are S4 classes, there are "irts" in package tseries "zoo" in package zoo which are S3 classes for irregularly spaced observations. "its" is probably the most mature, "timeSeries" is - as Diethelm said - similar to the S-PLUS implementation and "zoo" has the advantage that time information can be of (almost) arbitrary class. The development version of zoo is due for release next week or so, contact me off-list if you want the current version.
