Note there are more use cases than a "retention policy" type thing in
having time based log rotation. 

"My laptop started acting up last tuesday, I should see whats in the
logs from then"

a) search each rotated journal file until you find last tuesday. 
or
b) run journalctl on last tuesdays log since it was rotated daily and
you can clearly see what one is tuesdays. 

"I'd like to run a daily report on my logs"

a) journalctl out the journal, figure out when the last day started,
cut things before that out. 
or
b) journalctl after the daily rotate on the previous days journal. 

"This thing might have messed up when I last booted... uptime shows 16
days"

a) Figure out what journal was from 16 days ago by hunting around. 
or
b) journalctl out the one from 16 days ago
