For really recent dates (same day), use the relative date stamp, while for old dates (year doesn't match), don't bother with time and timezone. Also add 'auto' date mode, which defaults to human if we're using the pager. So you can do git config --add log.date auto and your "git log" commands will show the human-legible format unless you're scripting things. Note that this time format still shows the timezone for recent enough events (but not so recent that they show up as relative dates). You can combine it with the "-local" suffix to never show timezones for an even more simplified view. Signed-off-by: Linus Torvalds Signed-off-by: Stephen P.
