Asana data cache TTL readable duration is wrong beyond 24 hours

[MichelleBlanchette]

Using WordPress's human readable time diff function does not offer the best user experience since it doesn't go up to days, weeks, or months and always shows hours, minutes, and seconds even though some are 0.

It also seems if a duration extends beyond 24 hours (I'm guessing), then all values are 0 which is not correct.

I see now that it's actually just cutting off the day+ durations—or something like that—since implementing the more accurate display in #231

Old, wrong

New, correct
