• Minutes are removed for duration longer than a day
• Hours are removed for duration longer than a week

Examples :

 Util.formatDuration(Util.roundDuration(38000)); // 38 s
 => 38 s
 Util.formatDuration(Util.roundDuration(76000)); // 1 min 16 s
 => 1 min 16 s
 Util.formatDuration(Util.roundDuration(1564512)); // 26 min 4 s
 => 26 min
 Util.formatDuration(Util.roundDuration(5890000)); // 1 h 38 min 10 s
 => 1 h 38 min
 Util.formatDuration(Util.roundDuration(33165000)); // 9 h 12 min 45 s
 => 9 h
 Util.formatDuration(Util.roundDuration(35025000)); // 9 h 43 min 45 s
 => 10 h
 Util.formatDuration(Util.roundDuration(130993000)); // 1 day 12 h 23 min 13 s
 => 1 day 12 h
 Util.formatDuration(Util.roundDuration(236158000)); // 2 days 17 h 35 min 58 s
 => 2 days 18 h
 Util.formatDuration(Util.roundDuration(731675000)); // 8 days 11 h 14 min 35 s
 => 8 days
 Util.formatDuration(Util.roundDuration(5934547000L)); // 68 days 16 h 29 min 7 s
