Display more granular offer expiration

[danieljperry]

The default setting for expiring offers is 7 days. When an offer's expiration time is displayed in the GUI, it only lists days when more than 1 day remains. A default offer's expiration time is thus very quickly listed as 6 days, even though something like 6 days, 23 hours, 59 minutes would be more accurate. This request is to show the expiration times more like the latter.
