TZ_CONVERT(1)TZ_CONVERT(1)NAMEtz_convert - Timezone converter from operating system tz format into
libical format used by Orage and several other calander tools.
SYNOPSIStz_convert [OPTION...] [INFILE]
DESCRIPTIONtz_convert is a command line tool, which can be used to convert
timezone data from so called tz binary format, usually used in
operating systems, to libical format, used by several calenders like
Orage.
There are several options available to only convert certain files or
files in certain directory. Or only convert part of the file and ignore
for example old data. It is also possible to add new timezone files,
which are based on old timezone data.
There are tools, which generate ical timezones data from tz source
database, but those are often not available for normal users and are
difficult to use. So often libical timezones are not upto date.
tz_convert reads directly the binary tz data and makes it possible to
keep libical timezones up to date. The tool is mainly meant to be used
by distro maintainers, but it should be easy and clear enough for all
users.
FILES
tz timezone files often can be found in directory /usr/share/zoneinfo.
For example Europe/Helsinki. libical timezone files needs to be where
you calendar can find them. For Xfce and Orage systems they are located
under your Xfce directory in share/orage/libical/zoneinfo. For example
Europe/Helsinki.ics. (use locate to find them.)
OPTIONS-V, --version
Print version information and exit.
-?, --help
Show this help message and exit.
--usage
Show short usage summary.
-i, --infile
tz file name from operating system to convert from. If this is
directory, all files in it are processed. Default is
/usr/share/zoneinfo
-o, --outfile
ical timezone file name to be written. This can not be directory.
It is meant to be used together with timezone parameter. This is
very seldom used. Default is timezone/infile.ics
-m, --message
debug message level. How much exra information is shown. 0 is least
and 10 is highest (1=default). May give usefull information when
things do not work as expected.
-l, --limit
limit processing to newer than this year. Often there is a lot of
old data available, which is not needed in normal day to day work
and skipping unused years helps to improve performance. Default is
to ignore older than year 1970 time changes.
-t, --timezone
timezone name to be used in the actual file. Normally file name is
the same as timezone name, but if you want to create your own
timezone, you need new file name, which contains some known
timezone name. This is used together with outfile parameter.
-r, --norecursive
process only main directory, instead of all subdirectories. 0 =
recursive 1 = only main directory (0=default).
-c, --exclude count
number of excluded directories. 5 = default (You only need this if
you have more than 5 excluded directories). This is used together
with exclude parameter.
-x, --exclude
do not process this directory, skip it. You can give several
directories with separate parameters. By default directories right
and posix are excluded, but if you use this parameter, you have to
specify those also. You need to use exclude count if you have more
than 5 exclude directories.
-u, --norrule
do not use RRULE ical repeating rule, but use RDATE instead. Not
all calendars are able to understand RRULE correctly with
timezones. (Orage should work fine with RRULE). 0 = use RRULE 1 =
do not use RRULE (0=default).
BUGS
Please report any bugs and enhancement requests to
http://bugzilla.xfce.org/. Note that tz_convert is part of orage so
bugs are reported against orage and component tz_convert. Usage related
questions can be sent to xfce@xfce.org email list.
