RE: [syslog-ng] Bugreport: Ver 1.9.5 problems with facility/level filtering
I didn't check but most probably he added the localtime(&when) call in get_local_timezone_ofs() to extract the seconds you are away from UTC, including DST handling. Unfortunately I do not understand enough of timezone handling to be much of a help here. Time is too a difficult subject for me to understand, so I'm glad it works most of the time :).

Hmm, the "correct" file I see has shown up in Solaris 10 ;) with the libbc:
http://cvs.opensolaris.org/source/xref/usr/src/lib/libbc/inc/i nclude/time.h
Tomorrow I'll have access again to a Solaris 8 machine where I could try compiling the source. Bazsi seems to be very busy these days, so we just have to wait for a bit ...

Well this is depressing.... I'm googling this, and found this: http://archive.apache.org/gnats/7902 I get the distinct impression that tm_getoff doesn't exist on Solaris 8 (although it appears that Sun finally added it later on, as it's obviously there in 10). I guess the Apache guys produced a Solaris-specific chunk of code to work around that shortcoming (and that's what the web page is discussing). If anyone has any clues as to how one might add the "later" (more capable) time functionality on Solaris 8, I'd obviously love to hear it, or it looks like I'm dead in the water for using the future version of syslog-ng at this point. (i.e. a possible patch, or external component, that has this extended capability.) Thanks! Marvin

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. http://docs.sun.com/app/docs/doc/817-5438/6mkt5pc7s?q=localtime&a=view 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.
