| 175813 | 2003-09-16 20:11:00 | Every 4 or so days i will put the clock in the bottom right-hand corner to to the correct time, but then in 4 or so days later it will become around about 15 minutes slower..what causes this and what needs updating..(CMOS?) | MrBeef (342) | ||
| 175814 | 2003-09-16 20:24:00 | Hi ya - I had the same problem (wind XP home) but mine was slowing daily until I got service pack 1 regards Bug :) |

If it misses some of these interrupts, the time counter doesn't get increased, so the time gets "slower". The usual cause is a low battery which causes the crystal oscillator to slow down. Of course there are crsytals which are high or low in frequency right from new. Some AT boards had a trimmer capacitor so you could adjust the clock to be exacly right. I don't think they do that now. :D |
