Hi I'd like to compile the zoneinfo files for an embedded system where I'd like to strip as much information as possible. I see that all the zoneinfo binary files take 6.1Mb: $ du -s -h /usr/share/zoneinfo/ 6,1M /usr/share/zoneinfo/ If I run the zic compiler, it produces the following file sizes for example for Europe/Paris, Europe/Amsterdam, Europe/Berlin: $ mkdir -p test $ zic -d test europe $ ls -l test/Europe/{Paris,Amsterdam,Berlin} -rw-r--r-- 1 pel pel 2917 2010-03-31 22:09 test/Europe/Amsterdam -rw-r--r-- 1 pel pel 2309 2010-03-31 22:09 test/Europe/Berlin -rw-r--r-- 1 pel pel 2945 2010-03-31 22:09 test/Europe/Paris Since I don't care about time zone rules in the past for my embedded application, I'd like to compile only the rules starting at year >= 2010 for example (in other words, I'd like to ignore all historical rules older than < 2010). I would then expect output binary files to become not only smaller, but also many of them should also identical since most countries in Europe follow the same rules nowadays (Europe/Amsterdam, Europe/Berlin and Europe/Paris in my above example should become identical). So I should then be able to create links to most of them. However, I don't see any command line option in the 'zic' compiler to let me compile rules from >= 2010 only, or am I missing something? I suppose that I could edit the input ASCII file 'europe', 'asia' (etc) to remove rules in the past, but it seems error prone (especially since input text files can be updated regularly). Is there a simpler solution? Thanks -- Dominique
