When raising a ticket you should be able to backdate/change the time the ticket is logged as being raised.
By default it should be the current time, but there should be an option to override it so you can say it should have been created a few hours ago.
This is useful if you worked on something earlier but didn't raise a ticket at the time e.g. away from desk, busy on another call etc.
Not a huge thing but it can be useful for SLA purposes or if a customer wants to know when work was actually carried out.
