+Currently, there is a NOTE for pins on Windows that looks like this:
+
+```
+		#STDOFF	2:05:08.9
+		#STDOFF	8:05:43.2
+		#STDOFF	7:36:41.7
+		#STDOFF	-0:25:21.1

+```
+
+This is not due to pins but rather to the [arrow](https://cran.r-project.org/package=arrow) package and a problem with [how it includes a time zone database](https://github.com/apache/arrow/issues/35594).
