Who is your target audience? If it's the entire world, then I'd have
two separate defaults based on location. Otherwise, pick the option
that is more likely to be the standard of the target user. The
usability issue of having a longer list does not outweigh the
usability issue of using the time standard with which the target user
is most familiar.
To follow convention, you should also consider allowing users to
select the minutes field as well, if the system allows this.
"In most countries, computers by default show the time in 24-hour
notation. For example, Windows XP activates the 12-hour notation by
default only if a computer's language and region settings are:
* Albanian
* English (only in Australia, Belize, Canada, Caribbean, Jamaica,
New Zealand, Philippines, Trinidad, South Africa, United States, and
Zimbabwe)
* Greek
* Spanish (only in Mexico and parts of South America)
* Swahili"
