ubernit: put this in the sole scope where it's used.

Actually this doesn't exist anymore. Changed a few things.

+
+int main(int argc, char** argv) {
+  // Retrieve events for the last 5 sessions.
+  SystemSessionEventFetcher fetcher(5U);
+  std::vector<SystemSessionEventFetcher::EventInfo> events;
+  if (!fetcher.FetchEvents(&events)) {
+    std::cerr << "Failed to fetch events." << std::endl;
+    return 1;
+  }
+
+  // Print the event ids and times.
+  for (const SystemSessionEventFetcher::EventInfo& event : events) {
+    base::Time::Exploded exploded = {};
+    event.event_time.LocalExplode(&exploded);
+    std::string time = base::StringPrintf(
+        "%d/%d/%d %d:%02d:%02d", exploded.month, exploded.day_of_month,
+        exploded.year, exploded.hour, exploded.minute, exploded.second);
+    std::cout << "Event: " << event.event_id << " (" << time << ")"
+              << std::endl;
+  }
+
+  return 0;
+}
