Hello all, In my fix from yesterday although the wall clock time was correct, the timezone was incorrect and the JVM was defaulting to a generic timezone which set the jvm's clock to the best guess of what a 'wall clock' would say the time was. Needless to say this eventually fails if you ever cross a daylight savings time boundry while the jvm is running. I have a better code fix now which I think will work for all cases and give the correct time and timezone. I now get the correct time and the timezone is "America/New_York" as I expect. Could everyone else please try this new change to see if it works in your timezone? My informal way to get this into the next patchset is here: in src/freebsd/native/java/lang/java_props_md.c at line 283 you'll find #ifdef __FreeBSD__ /*** XXX ***/ hasDST = local_tm->tm_isdst; offset = local_tm->tm_gmtoff; #else hasDST = daylight == 0 ? kStandard : kDaylight; offset = timezone / -60; /* Conventions reversed between UNIX & Java */ #endif change this to: #ifdef __FreeBSD__ /*** XXX ***/ hasDST = (local_tm->tm_isdst == 0) ? kStandard : kDaylight; /*** changed line ***/ offset = (local_tm->tm_gmtoff / 60) - (local_tm->tm_isdst == 0 ? 0 : 60); /*** re-changed line ***/ #else hasDST = daylight == 0 ? kStandard : kDaylight; offset = timezone / -60; /* Conventions reversed between UNIX & Java */ #endif Rob F To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
