Merge "Fix SyncResutl.delayUntil javadoc" into pi-dev

    /**

     * Used to indicate to the SyncManager that future sync requests that match the request's

     * Account and authority should be delayed at least this many seconds.

     * Account and authority should be delayed until a time in seconds since Java epoch.

     *

     * <p>For example, if you want to delay the next sync for at least 5 minutes, then:

     * <pre>

     * result.delayUntil = (System.currentTimeMillis() / 1000) + 5 * 60;

     * </pre>

     *

     * <p>By default, when a sync fails, the system retries later with an exponential back-off

     * with the system default initial delay time, which always wins over {@link #delayUntil} --

     * i.e. if the system back-off time is larger than {@link #delayUntil}, {@link #delayUntil}

     * will essentially be ignored.
