Allow for more flexible data entry for calendar event start/end time
It would be helpful if the selection fields for calendar event start times could match a wider range of text input to avoid excessive mouse clicks. At present, typing in the fields will automatically select one of the pre-set options in the list (i.e., "12:00 AM", "12:30 AM", and so on) based on an exact match of the text string. While this does allow for somewhat rapid selection in limited cases, i.e., for events starting at midnight and on the hour from 2 am to 9 am (allowing typing a single digit and then it autoselects), but then further selection must be entered precisely in the format HH:MM and then either "AM" or "PM" typed; using the up/down arrow keys is helpful but if it's an afternoon/evening event it pretty much requires the use of the mouse to be efficient. It would be preferable to allow for smarter detection of keyboard entries, for example ones omitting the colon (e.g., 800 AM), without a space (e.g., 1030 PM), based on a 24-hour clock (e.g., 2145), and so on. To clarify, this for the web-based calendar interface. Thanks for your consideration.

In other words, you should just be able to type "9am" or "13:30". This is a no-brainer.
