A simple and potentially ugly add-on that makes the "Received" time in in-game more precise. For example, "6 days ago" may become "6d 12h 13m 10s ago". There is no configurability to it, nor is there any localisation for other regions (sorry!). But, I know that I find it useful myself, and others have expressed interest, so here it is.
The add-on was intended to be more fully-featured and provide an exact date and time that the mail was received, but the various functions for time calculation provided in the API seemed to give conflicting and inaccurate results.
Many thanks to Jhenox, whose "CraftAutoLoot" add-on gave me the bare basics of how to create an add-on.
