I have added a dialog box which pops up when a user starts or stops tracking time on an issue with Phrequent. These dialogs allow the user to modify the time if it so happens that they forgot to either clock in or out.
I have also added a Note field in the dialog when a user stops tracking time. This allows them to enter a note about the time, and is entered into the database, but is currently (as far as I know) not visible anywhere in Phabricator.
I have made these changes according to the suggestions found in T3568
Also, upon clocking in or out, if the time entered is a future time, an error is returned and the user is asked to enter a valid time.
