Archived:DateField minutes part behaves incorrectly (Known Issue)
When a DateField is initialized with the setDate() method and the user subsequently edits both the hour and minute part of the field, the system still uses the original minute part for that field.
For example, the field is initialized with "07:45" and the user then edits it to be "09:00". The user can see the change on the screen but the system still sees the minute part to be "45" and uses that value when getting the minutes from the field.
There is no workaround for this issue.
