I have a date/time display format specified as follows: mm/dd/yy hh:mm.
1 Access displays times for single digit hours without padding with a leading zero, even though it correctly displays leading zeros on the date when needed. This causes the date/time display to be ragged.
2 For the year, it doesn't matter how one specifies the date custom format: mm/dd/yy, or mm/dd/yyyy, both display with 4 digits for the year.
