I would think that you would be better off using a text field (or two) and recording times in them.There is no way to do this in the UI currently. Alternatively there is a feature request at github by a robintoy.https://github.com/osTicket/osTicket/pull/3231That might meet your needs, but it would mean that you would have to alter the core source files. If you do this then the only one who can support your would be the author.
