I need to have field, that I can enter due date and due hours (not nessecary the same field, but it would be nice). I've seen, that there's possibility to change due date format in jira download via advanced settings but I can't find solution in Jira ondemand. I was thinking about using date time picker but I can't change input format (or I can't find it). Is it possible to have date and time due date field? Or if I would like to exchange included due date field to custom date time picker what other Jira settings to I have to change so that Jira would still work?
