I compiled the small program (bugtest.c) mentioned in the letter below using the latest elsie.nci.nih.gov source; the program ran okay. As Scott mentions, folks on the mailing list probably do need to be aware of the bug. --ado From: Scott Harrington [SMTP:seh4@ix.netcom.com] Sent: Friday, November 06, 1998 1:16 PM Subject: BUG: Solaris mktime with multiple timezones I have posted the attached message to comp.unix.solaris, so replies should probably be posted there. I wanted to notify this mailing list since the bug affects those who use multiple time zones in their programs... I have uncovered a bug in the mktime() routine found in libc.so.1 and libc.a on my SunOS 5.5.1 Generic_103640-12 sun4u sparc SUNW,Ultra-2 machine: -rw-r--r-- 1 bin bin 1155756 Jun 23 1997 /usr/lib/libc.a -rwxr-xr-x 1 bin bin 664760 Jun 23 1997 /usr/lib/libc.so.1 I have attached a small program which should determine if your system has the bug or not.
