Обсуждение: British Double Summer Time

I dumped a 7.1devel database, and when reloading into postgres of 31 Oct
2001 20:23 GMT I get:

psql:foobar.db:60: ERROR:  copy: line 2247, Bad timestamp external
representation 'Fri 01 Aug 00:00:00 1941 BDST'
psql:foobar.db:60: lost synchronization with server, resetting connection

My zoneinfo files know about BDST, but src/backend/utils/adt/datetime.c
doesn't...

This may have been fixed within the last few days, and when I get to the
office I could see what changed in datetime.c, but I thought I would mention
it now..

Cheers,

Patrick

In 6 years of date/time work, this is the first I've heard of "BDST".
Can you give me a definition? What is the "double" part of it?? Does it
actually stand for "British Daylight Savings Time"?

Not fixed yet, but I found the definition of BDST on line, and will
commit it soon.

If you need a fix earlier, here is a patch...
