Hi Julian,

take the date as rev. parameter, see `svn help log'

Time for a working practical example, pick a FreeBSD mirror from https://www.freebsd.org/doc/en/books/handbook/svn.html.
We will run the command in a fresh empty dir (not part of any existing svn workspace)

$ mkdir /tmp/svnlogfoo && cd /tmp/svnlogfoo
$ svn log -qv -r '{2011-12-28}':'{2011-12-29}' http://svn0.eu.freebsd.org/ports
.... (log data we need to find the removed port)

I always start with sparse checkouts and use then `svn update' with the "--set-depth" parameter
For this example we re-use the empty /tmp/svnlogfoo directory
Lets see if we are able to checkout old data (e.g CVSROOT).

$ svn co --depth empty https://svn0.eu.freebsd.org/ports/head /tmp/svnlogfoo/
$ cd /tmp/svnlogfoo
$ svn info
Path: .
Working Copy Root Path: /tmp/svnlogfoo
URL: https://svn0.eu.freebsd.org/ports/head
Relative URL: ^/head
Repository Root: https://svn0.eu.freebsd.org/ports
Repository UUID: 35697150-7ecd-e111-bb59-0022644237b5
Revision: 375797
...

$ svn ls -r 10
CVSROOT/
Makefile
Mk/
editors/
shells/

$ $ svn up -r 10 CVSROOT
$ ls -1 CVSROOT/
commit_prep.pl
commitcheck
commitinfo
cvs_acls.pl
editinfo
log_accum.pl
loginfo
rcsinfo
rcstemplate

Lets see if we can check out mail/demime (r288195)

$ svn up --set-depth empty mail
Updating 'mail':
A    mail
Updated to revision 375797.

$ svn up -r288195 mail/demime
Updating 'mail/demime':
A    mail/demime
A    mail/demime/distinfo
A    mail/demime/pkg-descr
A    mail/demime/pkg-plist
A    mail/demime/Makefile
Updated to revision 288195.

Tada, we have the latest version from the demime port recovered in less then two minutes with a total checkout less then 200K

$ du -h -d1 /tmp/svnlogfoo/
124K    /tmp/svnlogfoo/.svn
 12K    /tmp/svnlogfoo/mail
 38K    /tmp/svnlogfoo/CVSROOT
176K    /tmp/svnlogfoo/

Since we do not need CVSROOT (was only an example checkout) we remove it from the workspace with the following update command to keep the sparse checkout tiny

$ svn up --depth empty CVSROOT
Updating 'CVSROOT':
D    CVSROOT

Hope the example will answers your question 2 and 3, I'm not sure about question one.
