In the Due Date and Time pop-up window, the Time field could be more helpful. I believe people mostly input whole hours there, and I certainly do. However, when I type a whole number and leave the field, it is converted to a number of minutes after midnight, which is unhelpful to say the least. I need to type either an am/pm indicator, or a colon and a zero to have the field do what I want.
When numbers between 0 and 23 are input in the field, it would be better to convert them to a number of hours.
7 gives 12:07 am (or 00:07 in 24-hour time format)
21 gives 12:21 am (or 00:21 in 24-hour time format)
30 gives 12:30 am (or 00:30 in 24-hour time format)
7 would give 7:00 am (or 7:00 in 24-hour time format)
21 would give 9:00 pm (or 21:00 in 24-hour time format)
30 would still give 12:30 am (or 00:30 in 24-hour time format)
I understand inputting 21 and getting 9pm could be surprising to people not used to that, but would this be worse than getting 12:21am?
