We have a list of items, with one of the attributes being a time duration. (Imagine users, and avg time between certain activities).
Most of the time, this duration will be in the 0->120 second range. Some times, it will jump into minutes, possibly hours, ... and rarely (but it's possible) the duration could be in the days.
Where we're at now is a display like "2h 43s", "2d 15h", "21s", "8d 2h".. But, if you put all those into a list, a problem arises because it's not immediately clear that you have a long duration sitting in the midst of a bunch of shorter ones, since "2d 15h" is the same length as "2h 43s"
Adding seconds/minutes to the "2d 15h 00m 11s" seems right to ensure the days "stick out" and keeps all the elements aligned.. But I'm not sure. That's a lot of added noise.
