Re: [xslt] Fail build of OpenBSD

[Charlie Bozeman <cbozeman HiWAAY net>]

I had the same problem in cygwin; I just changed timezone to _timezone
to get it to compile.
I am in the process of implementing the EXSLT date funtions and ran into
the same problem between cygwin at work and linux at home. Here is a
snippet of code that illustrates how I get the timezone offset:
{
    struct tm  *pLocalTm;
    struct tm  *pGmTm;
    time_t      tzSecs;        /* timezone offset in seconds */
    time_t      secs;

    newDate->format = format;

    /* get current time */
    secs     = time(NULL);
    pLocalTm = localtime(&secs);
    memcpy(&newDate->tm, pLocalTm, sizeof(struct tm));

    /* get real year, not years since 1900 */
    newDate->year = newDate->tm.tm_year + 1900;

    /* determine the time zone offset from local to gm time */
    pGmTm        = gmtime(&secs);
    tzSecs       = mktime(pGmTm) - secs;

This is a little inefficient so a portable solution using a variable
that holds the offset (_timzone or timezone) would be welcome.
