The following:

print date( "r Z T", time() );
print gmdate( "r Z T", time() );

Gives this output:

Tue, 14 May 2002 22:56:09 +0100 3600 GMT
Tue, 14 May 2002 21:56:09 +0000 0 GMT Standard Time

Comment:

Internally solaris creates an integer named
daylight after localtime() is called if an
alternate time zone is in use.

PHP ignores this and always uses tzname[0]

Quick fix:

diff ext/standard/datetime.c~ ext/standard/datetime.c
256c256,259
<               tname[0] = tzname[0];
---
>               if( daylight )
>                tname[0] = tzname[1];
>               else
>                tname[0] = tzname[0];

After patching the PHP code produces:

Wed, 15 May 2002 00:13:40 +0100 3600 BST
Tue, 14 May 2002 23:13:40 +0000 0 GMT Standard Time

The quick fix may only be valid for the UK (GMT/BST)

The altzone offset may be a better indicator that GMT
is not the correct local timezone elsewhere.

Thank you for taking the time to report a problem with PHP.
Unfortunately your are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

It would be even better, if you could retest with a CVS-snapshot.

Thanks for your help.
