>(the UK will then be in line with other parts of Europe).

Yes.  See ftp://elsie.nci.nih.gov/pub/tzdata96f.tar.gz for details.
You can use this for your new `europe' file, if your `zic' is sufficiently
up-to-date.  (If it isn't, get tzcode96e.tar.gz and use its `zic'.)

Actually, the UK rule changed in 1990 to be the first Sunday on or after 10-22.
The two rules had identical effects until last year.

And there was an earlier rule change in 1981 that changed the autumn
switchover time from 03:00 to 02:00.

They don't always, but in this case they did.
The new rule, the 7th EC summer time directive,
was announced by the EU on 1994-05-30 (94/21/EC)
and was confirmed by the UK on 1994-11-16 (SI 1994/2798).

OK. For those of us stuck using the TZ variable, the information from
the file mentioned above seems to condense down to:

TZ=GMT0BST,M3.5.0/01:00,M10.5.0/02:00

i.e. change forward on last Sunday in March, 0100 hours local (=GMT)
     (i.e. 0100 -> 0200)
     change back on last Sunday in October, 0200 hours local (= 0100 GMT)
     (i.e. 0200 -> 0100)

This rule to be effective from 1996 onwards.

Can anyone confirm that I got this right?

[no follow-up discussion of relative merits of TZ and zic please]

"No, I wouldn't say so; it is not that well organised..."

 
 
 

1. Daylight Savings time in the UK

The problem is simple.  It takes an act of parliament to change the time
from GMT to BST (British Summer time).  Needless to say localtime() is
firmly stuck in the North American way.  Thus, many computers in the UK are
fudged by hand for the week or so that the US and UK are out of sync.

Have there been any changes to localtime(), or the TZ environment variable
to cope with this mess; I've seen some horrible things done to the TZ
variable in Brussels (lots of semicolons and numbers afterwards), but
wondered if there was any proper standard.

Thanks in advance.
