HI all
we set the balancingWindow like below

db.settings.update({_id:"balancer"},{$set:{activeWindow:{start:"15:00",stop:"16:00"}}},{upsert:true})

But found out that the migrate and balancing is still working outside the activeWindow.

And then check the source code of balancing.

I found out the source code in "mongo/src/mongo/s/grid.cpp" is like below:

bool Grid::shouldBalance(const SettingsType& balancerSettings) const {

    if (balancerSettings.isBalancerStoppedSet() && balancerSettings.getBalancerStopped()) {

        return false;

    if (balancerSettings.isBalancerActiveWindowSet()) {

        boost::posix_time::ptime now = boost::posix_time::second_clock::local_time();

        return balancerSettings.inBalancingWindow(now);

    return true;

It looks like whether the time is outside the activeWindow or not ,the return is always "true"
