Follow date and time format set in Drupal

Issue Summary

Fist and foremost, thanks for a great module!

There is only 1 request that I hope you consider :-)

Sunrise: 5:49 +0800
Sunset: 17:49 +0800
1. In country specific sites that do not change time zones per city, it's kinda weird to see the +0800. Regular local users wouldn't understand the +0800 as they have never checked the time in relation to GMT.
2. Not all countries use the 24H time format, and would have preferred the am/pm format

So, is it possible to display the time like the format set by the admin in http://example.com/admin/settings/date-time ?

Thanks! :-)
