应用程序中的location更新问题

在我的应用程序中，创建了一个 location manager，每十分钟来更新一次当前的location。
但结果是每5分钟更新一次。

12-12 23:45:17.153: DEBUG/TheApp(2025): Location updated with accuracy: 48.0m
12-12 23:50:23.162: DEBUG/TheApp(2025): Location updated with accuracy: 48.0m
12-12 23:55:23.074: DEBUG/TheApp(2025): Location updated with accuracy: 48.0m
12-13 00:00:23.077: DEBUG/TheApp(2025): Location updated with accuracy: 48.0m

这是我设置的代码：

LocationManager locationManager = (LocationManager)
                   this.getSystemService(Context.LOCATION_SERVICE);

LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        Log.d(APP_TAG, "Location updated with accuracy: " + location.getAccuracy() + "m");
    }
    //Other methods are empty and omitted for brevity
};

int TEN_MINUTES = 10 /*Minutes*/ * 60 /*sec per min*/ * 1000 /*ms per sec*/;
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 
                                         TEN_MINUTES, 0, locationListener);

为什么不是每十分钟更新一次，而是五分钟更新一次呢？大家能帮忙解释一下这个问题吗？

if(System.CurrentTimeMillis() > updateTime + currentTimeInMillis)
{
 update your log here
 currentTimeInMillis = System.CurrentTimeMillis();
}
