rlog -zLT sometimes displays wrong date

[Oliver Billmann]

Hi,

I stumbled over a strange behaviour with rlog from the current 5.8 version.

Calling "rlog -zLT '-d>2011-05-04' RCS/user.sql,v" with user.sql,v
containing

> 1.13
> date    2011.09.30.15.39.03;    author oliver;  state Exp;
> branches;
> next    1.12;

displays the following:

on a Gentoo Linux i686 machine:

> revision 1.13
> date: 2011-09-30 17:39:03+02;  author: oliver;  state: Exp;  lines: +4 -4
> Neue Spalte SessionFlag belegen...

on a Gentoo Linux x86_64 machine:

> revision 1.13
> date: 2011-01-01 16:39:03+01;  author: oliver;  state: Exp;  lines: +4 -4
> Neue Spalte SessionFlag belegen...

Note the incorrect date.

After some debugging it looks like a variable not being initialized
correctly: t.tm_yday in rcstime.c:date2str is not set but will be used
in tm2time if TM_LOCAL_ZONE is requested. On the i686 machine it was
"initialized" with some large negative number which will than lead to
tm_yday being initialized in tm2time. But on the x86_64 machine it
contained the valid value 0 which than always leads to YYYY-01-01 ...

The following patch should fix it:

--- src/rcstime.c.org   2011-01-15 18:16:30.000000000 +0100
+++ src/rcstime.c       2011-11-10 14:13:02.164010596 +0100

      zone = BE (zone_offset.seconds);
