           Summary: MarbleClock initialized with invalid QDateTime
           Product: marble
           Version: unspecified
          Platform: unspecified
        OS/Version: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: general
        AssignedTo: marble-bugs at kde.org
        ReportedBy: jaimes at optech.ca


Version:           unspecified
OS:                All

The MarbleClock class modifies its m_datetime variable on a timer but this
variable is not initialized to a proper value on construction.

In the marble application this is not a problem because somewhere this variable
is set with a call to MarbleClock::setDateTime().

However, on a marblewidget based application if the same isn't done then this
causes odd behaviour. For instance the stars background will jump around
randomly because MarbleClock reports random times (Observed on WinXP with Qt
4.7.1).

Suggest initializing m_datetime variable to the current date time or
documenting the fact that it must be set explicitly.


Reproducible: Always

Steps to Reproduce:
Create a basic marblewidget application from any of the tutorials. Zoom out to
see the stars and watch them jump around randomly when the map is repainted.
