This is primarily intended for framework-level processing; consider using
RequestContextUtils
or
RequestContext
for
application-level access to the current locale and/or time zone.
The returned context may be a
TimeZoneAwareLocaleContext
,
containing a locale with associated time zone information.
Simply apply an instanceof
check and downcast accordingly.
Custom resolver implementations may also return extra settings in the returned context, which again can be accessed through downcasting.
