Date and Time Manager (mate-time-admin) does not let user set time/date manually if no ntp sync daemon is installed or activated

[mesov]

*Expected behaviour*

If no ntp sync daemon is installed, or if ntp sync is disabled, system time can be set manually by clicking on the "+" and "-" buttons, and date by clicking on the calendar.

*Actual behaviour*

If no ntp sync daemon is installed, or if ntp sync is disabled, the "Time" and "Date" fields are greyed, and the buttons to set time are disabled.

- if no ntp sync daemon is detected, switching the NTP sync button back and forth has not effect.

- if a sync daemon is installed but disabled, switching it on and off makes it possible to use the "+" and "-" buttons to set time manually, or to click on the calendar to change the date, until the Time and Date Manager is closed. After it has been closed and opened again, ntp sync needs to be switched on and off again in order to be able to set time/date manually.
