Fix issue #1769910 (Track activity launch times)
The usage stats service now collects per-activity launch time stats. There are a number of fixes and improvements to its statistics management and collection; it now operates its calendar in GMT and ensures that for checkin purposes it always reports one day and only one complete day to the checkin service.
Also change the checkin option from "-c" to "--checkin" since it is really a special thing.
