+class RTzdb(RPackage):
+    """Time Zone Database Information.
+
+    Provides an up-to-date copy of the Internet Assigned Numbers Authority
+    (IANA) Time Zone Database. It is updated periodically to reflect changes
+    made by political bodies to time zone boundaries, UTC offsets, and
+    daylight saving time rules. Additionally, this package provides a C++
+    interface for working with the 'date' library. 'date' provides
+    comprehensive support for working with dates and date-times, which this
+    package exposes to make it easier for other R packages to utilize. Headers
+    are provided for calendar specific calculations, along with a limited
+    interface for time zone manipulations."""
