> I've seen a lot of users getting confused by the TTL configuration and I think that if we just pretty printed it it would solve most of the issues. For example, let's say a user wanted to set a TTL of 90 days. That would be 7776000. But let's say that it was typo'd to 77760000 instead, it gives you 900 days!
> So when we print the TTL we could do something like "x days, x hours, x minutes, x seconds (real_ttl_value)". This would also help people when they use ms instead of seconds as they would see really big values in there.
