commit a4c85312604c1d215f9f46a24ac242baf666ed56
Author: Caio Valente <valentecaio95@xxxxxxxxx>
Date:   Wed Jan 31 02:36:38 2018 +0100

    refactor: using get_uptime() (and reset_uptime()) consistently.
    
    Using get_uptime() and reset_uptime() instead of
    accessing stats_n_seconds_working directly.
    
    stats_n_seconds_working is not extern anymore.
    
    Ticket #25081
