but usually I look in the log to figure out what is the revision number.

There is no need for a separate command because any command that takes a revision number can
also accept a date and time. If no time is specified, the time is midnight. Subversion then
uses the newest revision that precedes the given date and time. For example, if I request
to check out MacPorts code from midnight October 10, 2002:

$ cd /tmp
$ svn co https://svn.macports.org/repository/macports/trunk -r '{2002-10-10}'
$ cd trunk
$ svn info
Path: .
Working Copy Root Path: /private/tmp/trunk
URL: https://svn.macports.org/repository/macports/trunk
Relative URL: ^/trunk
Repository Root: https://svn.macports.org/repository/macports
Repository UUID: d073be05-634f-4543-b044-5fe20cf6d1d6
Revision: 1025
Node Kind: directory
Schedule: normal
Last Changed Author: jpm
Last Changed Rev: 1025
Last Changed Date: 2002-10-09 22:38:38 -0500 (Wed, 09 Oct 2002)

I get revision 1025, the newest revision that is not after midnight October 10, 2002.
