</verbatim>
Here the value of TZ is a filename path; if it doesn' begin with a __/__, then it is interpreted relative to the __/usr/share/zoneinfo__ directory (on most Linux distros). Multiple files in this directory with the same contents give different ways of specifying the same time zone; thus __NZ__ is a synonym for __Pacific/Auckland__.
+
+Note that setting __TZ__ in this way can also be used on other commands that show dates/times, such as ls(1), the abovementioned __perl__ and __convdate__ examples etc.
