Nice.

Exactly. Here is the full code which seems to work around those issues 
rather nicely (you're in for a good treat reading the comment block 
almost at the end of the code):

http://svn.apache.org/viewcvs.cgi/apr/apr/trunk/time/unix/time.c?view=markup

I wonder if this should be implemented in syslog-ng as well? Browsing 
through the whole httpd code of Apache reveils a very thoughtful 
designed cross-platform implementation of concepts in many aspects of 
ancients disputes in Unix history.

I have an idea, but distinct lack of time right now. Bazsi is in Sevilla 
enjoying the sun and giving interesting speeches at the present time ;). 
He has a lot to fix when he comes back.

Could you grep for this tm_gmtoff and altzone as follows, please (maybe 
it's defined as __tm_gmtoff)?

find /usr/ -type f -name "*.h" -exec grep "tm_gmtoff" /dev/null {} \;
find /usr/ -type f -name "*.h" -exec grep "altzone" /dev/null {} \;

But chances are little. Reading man page of SunOS 8/04 localtime(3C) I 
could find:

      The value of tm_isdst is positive if daylight  savings  time
      is  in  effect,  zero  if  daylight  savings  time is not in
      effect, and negative if the information  is  not  available.
      Previously, the value of tm_isdst was defined as non-zero if
      daylight savings was in effect.

      The external time_t variable altzone  contains  the  differ-
      ence, in seconds, between Coordinated Universal Time and the
      alternate time zone. The external variable timezone contains
      the  difference,  in seconds, between UTC and local standard
      time.  The external variable daylight indicates whether time
      should  reflect  daylight  savings  time.  Both timezone and
      altzone default to 0 (UTC). The external  variable  daylight
      is  non-zero if an alternate time zone exists. The time zone
      names are contained in the external variable  tzname,  which
      by default is set to:

           char *tzname[2] = { "GMT", "" };

      These functions know about the peculiarities of this conver-
      sion  for  various  time periods for the U.S. (specifically,
      the years 1974, 1975, and 1987). They start handling the new
      daylight  savings  time  starting  with  the first Sunday in
      April, 1987.

So, in fact, it could be done for your system as well. I should know 
since I live in a country where time means everything to the its people 
;). They even apologize to you at the railway station through the 
loudspeakers if the train departure is delayed by more than 3 minutes.

Have a nice one,
