The existing implementation fails to determine the correct time zone abbreviations when the display language is non-English. This change adds support for localized time zone names (standard- and daylightname) by using the function RegLoadMUIString. Fixes #12015 Change-Id: Ic0dc89c50993af8f292b199c20bc5932903e7e87 Reviewed-on: https://go-review.googlesource.com/13854 Reviewed-by: Alex Brainman <alex.brainman@gmail.com> Run-TryBot: Alex Brainman <alex.brainman@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org>
