I made a patch which adds a new function, svn_time_to_human_nts, and
then uses it for the places where the date format is mangled for user
display.
The actual format of the date stamps is:
2002-06-22 11:14:42 +03:00
The format can - and should - be changed if a real consensus is gotten
for the format.
The dubious part is 'svnlook'. Should that use this same function?
This means that TZ needs to be set very carefully for it. I'd want
some input on this.
I'll probably work a bit more on the patch - and then commit it if it
is deemed as a good thing. But, without further ado, on to examples
and the patch.

Log message:
Added a new function, svn_time_to_human_nts, that handles converting
apr_time_t into a human representable time format. Then made 'svn log',
'svn info' and 'svnlook' use it.
* subversion/include/svn_time.h
(svn_time_to_human_nts): New prototype.
* subversion/libsvn_subr/time.c
(human_timestamp_format): New variable.
(svn_time_to_human_nts): New function.
* subversion/svnlook/main.c
(do_date): Use svn_time_to_human_nts.
* subversion/clients/cmdline/log-cmd.c: Include svn_time.h.
(humanize_date): Remove function.
(log_message_receiver): Use svn_time_to_human_nts.
* subversion/clients/cmdline/info-cmd.c: Include svn_time.h.
(svn_cl__info_print_time): Add pool argument.
(svn_cl__info_print_time): Use svn_time_to_human_nts.
(svn_cl__info): Give pool to svn_cl__info_print_time.
