nit: It is possible to place here each parameter per line, will be much more
readable.

Is this code clang formatted?

[Alexander Alekseev, 2014/05/22 19:13:32]

Ye, it is a result of clang-format.

done.

nit: dot at the end.

[Alexander Alekseev, 2014/05/22 19:13:32]

NetworkPortalDetector launches tasks when default network state is "online".
TimeZone resolve is started via DelayNetworkCall(), which uses
NetworkPortalDetector.
