    Well I'll be damned. It took 18 days to show up. Though I've been
    riding this baby heavy for about a week.
    So I've gettimeofday() jumping backwards again.

    # uname -a
    Linux tienel 2.6.0-test9 #2 SMP Sun Oct 26 14:35:02 EET 2003 i686 GNU/Linux


    It's this test I'm running (snipped from previous TSC desych
    -conversation):

    - -
    #include <stdio.h>
    #include <sys/types.h>
    #include <sys/time.h>

    int main( void )
    {
    int i = 0;

    while( 1 )
    {
    struct timeval start;
    struct timeval stop;
    struct timeval diff;
    int rc1;
    int rc2;

    if( i++ % 1000000 == 0 )
    printf( "% 12d: Iterations so far\n", i );

    rc1 = gettimeofday( &start, 0 );
    rc2 = gettimeofday( &stop, 0 );
    timersub( &stop, &start, &diff );

    if( rc1 < 0 || rc2 < 0 )
    printf( " %12d: rc1=%d rc2=%d. Failure!\n",
    i,
    rc1,
    rc2
    );

    if( diff.tv_sec >= 0 && diff.tv_usec >= 0 )
    continue;

    printf( "% 12d: Time went backwards: %d:%06d\n",
    i,
    diff.tv_sec,
    diff.tv_usec
    );

    }
    }
