Military Time Entry in Date/Time Fields

I have all the time on all my devices set to use military time. When I attempted to enter 0900 in an OmniFocus form it reverted to 5:00 PM. I had to enter 9:00 AM into the field. Is this a flaw?

Thanks.

Try going to System Preferences, Language & Regional Format, Time Format & checking the 24 hour box

I also found that if you put a colon between the hour and minutes (09:00) it will display the correct time. I also tried 21:35 and it found/converted the time properly (it displayed as 9:35 PM).

I wish there was less friction in entering the task, but I guess using a colon is still faster than entering AM/PM.

I hope this helps!
