Re: [xml] date-time strangeless last night

Last night, date:seconds() started returning invalid values. To test I

<xsl:value-of select="date:seconds()"/>

It printed a time from the day before.  Coincidentally, this started 
happening after 8pm EDT which would be when my time was in September and 
the GM time was in October.  The code (line 791 of 1.1.17) looks pretty 
suspicious to me:

     ret-> = (((ret-> * 1440) +
                             (ret-> * 60) +
                              ret-> -
                            ((gmTm->tm_mday * 1440) + (gmTm->tm_hour * 60) +

which seems to be computing the seconds between localtime and gmtime.  With 
no mention of month I can't see how that is right...  I assume something 
similar but worse will happen at the end of the year.

I can reproduce this problem by adding

secs = 1159664596;

immediately after the call to time(NULL) in exsltDateCurrent while running 
the software on a machine in EDT.  When I do this, the value of tzo is 2000 
while the correct value should be -240.

  Okay, sounds like a bug, make sure you were using the latest libxml2
as some ofddities in date and time have been fixed in the last year, and
if this is the case please create a bugzilla entry.

  thanks !
