Alternative Speed Limits Scheduled Times broken in transmission-qt

On 32-bit and 64-bit systems, preferences dialog for 'Speed > Alternative Speed Limits > Scheduled times' always shows 00:00 to 00:00 whenever invoked. Setting times using gui spinners increments the times, but upon closing the dialog and returning to it in the same session, they are back at 00:00 to 00:00.

Manually editing settings.json while transmission is not running, e.g.: "alt-speed-time-begin": 540, "alt-speed-time-end": 1380, ...will be unchanged when transmission-qt launches. However, if the preferences dialog is invoked it will show 00:00 to 00:00. If changed, it will show the changes but only until the dialog is called again, whereupoin it will again show 00:00 to 00:00.

Worse, upon exit, transmission-qt overwrites the changes made to settings.json *while transmission was not running*, resetting both values to 0.

This bug was apparently introduced sometime after svn trunk 2.82+ (14205).

Current svn trunk builds 2.84+ (14327) and (14328) were created using Fedora 20 32-bit and 64-bit systems using qmake-qt5.

This bug is present in the kubuntu 15.04 AMD64 version as well. Please advise... Thank you Lonnie
