There was power outage, but now it's OK.
How can you determine its moment? Time now is 19:42. Your home router's uptime is 3h53m.
>>> now=19*60+42 # 19:42 >>> uptime=3*60+53 # 3:53 >>> minutes_from_0000_router_started=now-uptime >>> minutes_from_0000_router_started//60 15 >>> minutes_from_0000_router_started % 60 49 >>>
So it was 15:49 when router started.
