stupid question: file dates?

["Marcel (Felix) Giannelia" <felix skeena net>]

Hi,

This seems like it'll have a really obvious answer, but I can't find it 
-- how do I show file modified dates? I'd also like to be able to see 
file sizes.

I've figured out that the little red dot on the icon means "this one is 
newer," but it's erratic -- sometimes I see a little red dot on two 
files with the same timestamp that are binary identical. Oh; I think I 
just figured that one out: ls -l --full-time shows that the file 
timestamps differ in the fractions of seconds. Must've gotten truncated 
by scp or by spending time on a filesystem with lower time resolution.

Anyway, sometimes I'd really like to know "how much newer", because if 
it's within 8 hours of each other I don't know if it's really newer, or 
if it's just that the file has been on a computer with its time zone set 
wrong (some of the machines at the university are not reliable that way).
