Timesync.serverTime running each sec in nonReactive mode

I want to access server time on client side though only when queried for. So I have a function to get the current server time non-reactively:

```
getServerTime = function() {
var serverTime;
if (!TimeSync.isSynced()) {
TimeSync.resync();
} else {
serverTime = Deps.nonreactive(function() {
return TimeSync.serverTime();
})
}
return serverTime;
}
```

It used to work fine in meteor 0.8.3 but now I have upgraded to meteor 1.0 and TimeSync.serverTime runs continuously causing my subscribes to run infinitely.

Does it need some change for meteor 1.0?

Start by reproducing the shown getServerTime function with Meteor 1.0, focusing on TimeSync.serverTime(), TimeSync.resync(), and Deps.nonreactive(). Compare whether serverTime remains reactive and identify why subscriptions rerun continuously; done means a non-reactive query returns server time without repeated subscription execution.
