The current timezone fact simply returns a timezone with no location information. A new fact, say timezone_name, which gets the current name from /etc/zoneinfo would be much more useful.
eg.
timezone_name => America/New_York
This might be difficult to make consistent across all operating systems, any community help would be appreciated.
One motivation for a new timezone fact (with a different name) is the current fact is ambiguous (e.g. CST) see FACT-1501.
