I suspect that it is only a problem for those whose machines are a) Having the CMOS clock set to local time (instead of UTC) and b) Having their computers turned off when the switch to/from DST is being made - thus preventing adjkerntz(8) from adjusting the CMOS clock appropriately. Running ntpd(8) will by itself not cause any problems - but in the above scenario it will not adjust the time to be correct either - the jump will be too large. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
