class Nightly(base.BaseScheduler, base.ClassifierMixin, TimedBuildMixin):
    """Imitate 'cron' scheduling. This can be used to schedule a nightly
    build, or one which runs are certain times of the day, week, or month.

    Pass some subset of minute, hour, dayOfMonth, month, and dayOfWeek; each
    may be a single number or a list of valid values. The builds will be
    triggered whenever the current time matches these values. Wildcards are
    represented by a '*' string. All fields default to a wildcard except
    'minute', so with no fields this defaults to a build every hour, on the

    For example, the following master.cfg clause will cause a build to be
    started every night at 3:00am::

     s = Nightly(name='nightly', builderNames=['builder1', 'builder2'],
                 hour=3, minute=0)

    This scheduler will perform a build each monday morning at 6:23am and
    again at 8:23am::

     s = Nightly(name='BeforeWork', builderNames=['builder1'],
                 dayOfWeek=0, hour=[6,8], minute=23)

    The following runs a build every two hours::

     s = Nightly(name='every2hours', builderNames=['builder1'],
                 hour=range(0, 24, 2))

    And this one will run only on December 24th::

     s = Nightly(name='SleighPreflightCheck',
                 builderNames=['flying_circuits', 'radar'],
                 month=12, dayOfMonth=24, hour=12, minute=0)

    For dayOfWeek and dayOfMonth, builds are triggered if the date matches
    either of them. All time values are compared against the tuple returned
    by time.localtime(), so month and dayOfMonth numbers start at 1, not
    zero. dayOfWeek=0 is Monday, dayOfWeek=6 is Sunday.

    When onlyIfChanged is True, the build is triggered only if changes have
    arrived on the given branch since the last build was performed. As a
    further restriction, if fileIsImportant= is provided (a one-argument
    callable which takes a Change object and returns a bool), then the build
    will be triggered only if at least one of those changes qualifies as
    'important'. The following example will run a build at 3am, but only when
    a source code file (.c/.h) has been changed:

     def isSourceFile(change):
         for fn in change.files:
             if fn.endswith('.c') or fn.endswith('.h'):
                 return True
         return False
     s = Nightly(name='nightly-when-changed', builderNames=['builder1'],
                 hour=3, minute=0,
                 onlyIfChanged=True, fileIsImportant=isSourceFile)

    onlyIfChanged defaults to False, which means a build will be performed
    even if nothing has changed.

    compare_attrs = ('name', 'builderNames',
                     'minute', 'hour', 'dayOfMonth', 'month',
