Subject: [PATCH] Fix issue where the incorrect meridian would be selected.

When combining 12 hour format, interval and afternoon times, the
incorrect meridian would be selected.  Moving the hour math into
FormHelper::hour() makes that method generally more correct and lenient
on its input.

Fixes #3299
