Timezone

@ -24,3 +24,10 @@ Just search for the current or previous year and see what has changed.
Sometimes a country changes its time zone offsets, for example Georgia
in 2004. Just grepping in the zic database files for 2004 is enough to
spot such a change. Then the files under tznames/ should be updated.
When there has been a new release of Windows (probably including Service
Packs), the list of matching timezones need to be updated. Run the
script in src/tools/win32tzlist.pl on a Windows machine running this new
release and apply any new timezones that it detects. Never remove any
mappings in case they are removed in Windows, since we still need to
match properly on the old version.
