zic is not part of coreutils, but does belong to the GNU C library (glibc). See http://www.gnu.org/software/libc/bugs.html for bug report instructions.

Hi there,

Don't know if you'll want to fix, but we just had an issue where zic is generating files which cause a kernel panic in tzfile.c on Linux. Apparently the -01:00 is the offending time offset.

cheers,

We compiled the following timezone file with zic and put the result in /etc/localtime. This makes tzfile.c fail with assertion that numtypes==1.

# /etc/timezone (auto-generated)

# Daylight savings time rules
#    Name       YrStart   YrEnd   Type   Month,Day,At,Offset      Letter
Rule DAYLIGHT   2000      max     -      Mar lastSun 02:00 01:00   -
Rule DAYLIGHT   2000      max     -      Oct lastSun 03:00 -01:00   -

# Timezone description
#    NAME        Offset    Rule       Name(/DaylightName)
Zone localtime   00:00     DAYLIGHT   GMT/BST
