*provide a test of the generality of the local time rule description

system.

 

The information in the time zone data files is by no means authoritative;

the files currently do not even attempt to cover all time stamps before

1970, and there are undoubtedly errors even for time stamps since 1970.

If you know that the rules are different from those in a file, by all means

feel free to change file (and please send the changed version to

tz@iana.org for use in the future).  Europeans take note!

 

Thanks to these Timezone Caballeros who've made major contributions to the

time conversion package:  Keith Bostic; Bob Devine; Paul Eggert; Robert Elz;

Guy Harris; Mark Horton; John Mackin; and Bradley White.  Thanks also to

Michael Bloom, Art Neilson, Stephen Prince, John Sovereign, and Frank Wales

for testing work, and to Gwillim Law for checking local mean time data.

None of them are responsible for remaining errors.

Please send comments or information to tz@iana.org.

 

Postscript:  The README above is largely unmodified (aside from details

of mailing list and ftp archive addresses) from that prepared many years

ago by Arthur David Olson, to whom the timezone community owes the

greatest debt of all.  Arthur is not currently maintaining this data or

code (though he remains involved).
