[leafnode-list] Incorrect GMT offset in NEWGROUPS command

[Stefan Wiens <s.wi@xxxxxxx>]

When using the additional "GMT" in a NEWGROUPS command, leafnode does
not compute the timezone offset properly.

For example:

| 200 Leafnode NNTP Daemon, version 1.9.17 running at neon.eswe.dyndns.org
| newgroups 001029 160000
| 231 List of new newsgroups since 972831600 follows
| .
| newgroups 001029 150000 GMT
| 231 List of new newsgroups since 972824400 follows
| .

My local timezone is CET (GMT +0100), so both time specifications
should mean the same.

This also occurs in the 2.0b3 version and the NEWNEWS command.

For consistency with the libc "tm_gmtoff", I suggest the following
change to gmtoff() (to 2.0b3):

--- nntpd.c.orig        Fri Oct 27 18:00:53 2000
+++ nntpd.c     Sun Oct 29 16:41:43 2000

     putenv( oldzone );
     free( oldzone );

-    return( gmtsec - localsec );
+    return( localsec - gmtsec );
 }

 /*


Note that this is the reason why slrn sometimes seems to find the same
new groups on each invocation.
