Annotation of 43BSDTahoe/etc/tzone/README, revision 1.1.1.1

1.1       root        1: @(#)README     3.1
                      2: 
                      3: Please send comments or information to
                      4:        seismo!elsie!tz
                      5: for forwarding to folks interested in time zone matters.
                      6: 
                      7: Be sure to read the comments in "Makefile" and make any changes
                      8: needed to make things right for your system.
                      9: 
                     10: This version of the time zone software uses a new format
                     11: (based on the work of Guy Harris, a.k.a [email protected])
                     12: for the time zone information files.  They are now stored by default in a
                     13: directory named "/etc/zoneinfo" rather than "/etc/tzdir" or "/etc/timezones"
                     14: as before.  If you've already compiled programs with older time zone software,
                     15: just leave the "/etc/tzdir" and/or "/etc/timezones" files around until you
                     16: have a chance to recompile.
                     17: 
                     18: For better compatability with other versions of time conversion functions,
                     19: the time zone abbreviation to be used with localtime's return value is now
                     20: pointed to by one of the two elements of the (char *) array tzname, rather
                     21: than by the (char *) tz_abbr.  If you have code that uses tz_abbr, add a
                     22:        -DTZA_COMPAT
                     23: to the end of the
                     24:        CFLAGS=
                     25: line in "Makefile".
                     26: 
                     27: To use the new functions, use a "-lz" option when compiling or linking.
                     28: 
                     29: Historical local time information has been included here not because it
                     30: is particularly useful, but rather to:
                     31: 
                     32: *      give an idea of the variety of local time rules that have
                     33:        existed in the past and thus an idea of the variety that may be
                     34:        expected in the future;
                     35: 
                     36: *      provide a test of the generality of the local time rule description
                     37:        system.
                     38: 
                     39: The information in the time zone data files is by no means authoritative;
                     40: if you know that the rules are different from those in a file, by all means
                     41: feel free to change file (and please send the changed version to seismo!elsie!tz
                     42: for use in the future).  Europeans take note!
