roundDuration

public static long roundDuration(long duration)

Round a duration in order to remove irrelevant information for duration which do not need to be accurate (usually when duration is formatted for the UI).

As of current implementation, the following rules are applied

• Seconds are removed for duration longer than 5 minutes.

• 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
