The title is a bit obscure. This is the problem: If I forget to turn off my timer at the end of the day, it keeps running all night and into the next day. When I realise this has happened, it's added 30 hours or whatever to my timesheet. If I stop the timer at this point, open the Window and click on 'yesterday', when the timing started, I get a line that shows yesterday's date, the start time, and the current time (in this case 10.10), plus a total time in excess of 24 hours (see first image in attached file). So now I click on the end time and try to enter yesterday afternoon's actual end time (say, 15.43). When I do this, the timing still thinks the end date is today, not yesterday (second image in attached file). The only way I can convince it to move the time back to yesterday is to change the total hours from, in this case, 31h30m to, say, 8h0m, and then set the end time. It would be nice if, say, I could click on the little » character in the time range and have a pop-up menu that lets me tell it to move the time back to yesterday's date — or something like that.
