See section about locale generation.

This is something Boost general not related
to Boost.Locale specifically.

Take a look on libs/locale/examples

This specific "problem" would be added to FAQ.

Read the tutorial there are an examples how to make UTC, local timezone 
(default)
or custom time zone output (there is a manipulator for this purpose and 
formatting
flags).

Also the way you want to display dates is application specific and dependent
on use case.
