Hi,
I have a question about the internal of "git log". Each time when I
execute the following command:
> git log --numstat --since="2022-06-01" --until="2022-06-21"
--no-merges --format=%n%n%s%n%H%n%cs%n%an\<%ae
The number of the commits in the output is slightly different. I didn't
do any sync operation in the repo, so the only reason I can found is
that maybe git log involves some stochastic operations, so each time the
output will be a little changed. Is my assumption right?

The `--since` and `--until` date values use the *current time* if you do
not specify an exact time. For instance, "yesterday" means "precisely
24 hours ago" (86400 seconds ago), and "--since 2022-06-01" means
"since 1 June 2022 at whatever time of day it is right now". If you want
commits with timestamps that are since *midnight* on that day, include
the midnight part in the date.
(This is probably a UX bug, of sorts: to mean "at now-oclock on a given
date" we should probably have a syntax like "2022-06-21:(now)" and
when a specific date is given, the default should be midnight for "since"
and 23:59:59 for "until", or 23:59:60 if that's a leap-second date. But
changing this is probably not in the cards.)

Wonderful! That make sense that each time I do the calculation, the
result will be slightly different.
