Alex,
This is interesting, and thanks for digging it up.
Using this plist it appears that I could use [[NSUserDefaults standardUserDefaults] addSuiteNamed:@"com.apple.menuextra.clock"] and access this data with the key 'DateFormat'. I'm not sure I want to do this. I expect there is a degree of fragility. Apple could change the domain or the key. But, it's good to be able to consider it. With this I could find out how the user has there clock configured.
Although, here I'm not sure I should look for 'a'. Previously I was relying on the template functionality's response to the special token of 'j'. As your examples illustrate, the absence of 'a' could just indicate the preference of no 'period' in the format string. But the uppercase 'H' is a strong enough indicator.
Thanks again for your time and thoughts.
Sandor
