336017 2005-03-20 04:30:00 Hey there, I just want to know, how did my computer's (Win XP home edition) manage to synchronize the time with the outside world (I mean, the Internet) without asking my firewall's permission? Renmoo (66)
336018 2005-03-20 04:35:00 Don't know that it did, I think that it is just built into the software to drop an hour at the end of daylight saving. There is an option to set this up during the instal. I was on the computer, Win2KPro, and with no notification the time reverted during my usage but the system said nothing to me. On Win98SE you get a notification. zqwerty (97)
336019 2005-03-20 04:42:00 Don't think that synchronisation feature is meant for daylight saving thing only. Renmoo (66)
336020 2005-03-20 04:56:00 It knows the daylight settings from when you told it which region you were in. If you changed the region to China or anywhere else, it wouldn't have happened. The time sync is just for time , not date. pheonix (36)
336021 2005-03-20 05:00:00 I just moved onto Win98SE OS and there it was, a notification asking me to check the time was correct.
So you did actually activate some feature to synchronize your time to the outside world, which it did through the firewall without giving a warning etc? Is this what you are saying?

No, it is purely a software adjustment, it just changes your real time clock by one hour. If your real time clock is in error, then you will find out when you synchronise via an external time server.

XP doesn't say if it corrects for average ping time to the time server, as some other 3rd party synchronisation programs like '4th Dimension' do.

I getting confused, I thought that was what I said in the first place.

336025 2005-03-20 06:01:00 I used to use something called "Atomic" to synchronise the clock on my PC when I was still using Windows. It knew about daylight savings from the values you entered in the Windows time zone configuration.

If any of you are using Linux or *BSD, you can use a built-in service called ntpd (network time protocol daemon). Just set it up to poll 3 - 5 atomic clocks regularly (lots scattered throughout the Pacific rim) and your PC will keep perfect time.

336026 2005-03-20 06:11:00 :) Sorry zqwerty, it is me getting confused between your post and Jameskans. I meant to re-inforce yours that it is just a software alteration, not a synchronisation. Synchronisation is a separate operation. Terry Porritt (14)
