It requires that time be kept in UST to be useful and, from what I can tell, most folks keep time in their local timezone, thus, effectively, disableing the usage of the leapsecond correction (ntp figures this out and just says "no"). Possibly it is time to ask if we should keep this in the kernel at all. -- George Anzinger george@mvista.com HRT (High-res-timers): http://sourceforge.net/projects/high-res-timers/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
