Outstanding! I didn't notice a slowdown from the extra exec, but saving cycles isn't a bad thing if you don't have to sacrifice clarity.
I went a little bit crazy with this, and now have different formats for less than a day old, more than a day but less than a week old, more than a week but less than 30 days, and more than 30 days. I've attached it.
Here's a (censored) view of my index right before I started this message:

I think day boundaries would be possible with some work on the msg_age calculation, maybe "$(( ($now/86400) - ($msg_date/86400) ))"?
