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,
Jamie (address@hidden)
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
