Posted by ybw_Kingfisher Posts 7 Registered at 2008-10-03 09:15:26	2009-09-01 09:06:22 - Time zone bug
	I'm currently in Astana (UTC+7), instead of Brussels (UTC+2). What I do is I just change the clock of the computer, instead of changing my time zone. So I just move the clock forward 5hrs, while the time zone remains Brussls-Paris, otherwise Outlook starts to mess up my appointments. But when I look at the UTC clock in the Sailonline clock, it gives me UTC as Astana time minus two hours. Example: It is now 1500hrs in Astana, 10000hrs in Brussels, 0900 UTC. The clock tab on screen of the client gives 1300hrs as UTC. When I give a delayed command, I see in the list of timed commands that there the correct UTC is used. So let me guess: the time tab calculates UTC by taking the time of the PC and the time zone the PC is set against and then calculates the offset? WHile the timed commands use the actual time of the server? So if your computer and the server are out of synch, your delayed commands could be too? Rammed another island today, but that is because the predictive position in this game is still a game of pure chance.

	Do you have Windows Vista? There you can have 3 clocks if you left click on the time in bottom right of screen; Set (leave) your main clock @ Brussels time. set 2nd clock @ UTC and the third whereever you travel to and are at in the world. Try it. If it breaks, it's not strong enough!

	On second thought,I checked at http://tinyurl.com/ox3a6g (www.timeanddate.com) and it lists Astana as UTC+6 hours.

	To comment on your technical bit of the question, all times are UTC both on the client side as well as the server side. This is done to eliminate any time conversions. So there is no relation between the time displayed and the computers clock. The bigest factor in a incorrect delay is weather updates. They have a big influence on the speed and direction if on TWA. And there is a certain amount of error in the predicion line, due to rounding of numbers. Some of the interface like the prediction line, can give the impression to be exact but they do have some margins to take into account on the longer delays. --- Last Edited by Jeroen Tiel at 2009-09-01 11:11:45 --- I am a ex-admin of SOL who joins in from time to time.

Not so: I can give you a screenprint which shows 12:00 UTC on the main clock and a delayed command to be implemented at 09:30, so which technically is long passed.

	No its not just pure luck, as I explained there are some factors that can throw off a delayed command. On the short run they are reliable and on the long run they can be a bit less acurate. Its just a factor to take into account when you use them. I am a ex-admin of SOL who joins in from time to time.

	For those in the Antipodes it would be useful to see the date displayed with the time, so we can be sure actual time difference with local time. Especially handy for starting as a mix up in days/nights can waste places quickly.

	Had we started a race at: 09:09 on 09-SEP-09 we would have been without too much confusion!! If it breaks, it's not strong enough!

	a bit too much luck with all those 9's

Haida Gwaii 2024

We will end the second quarter of the ARCH competition with a 390nm race around the Haida Gwaii islands (literally "Islands of the Haida people"), also known as the Queen Charlotte Islands. This is an archipelago located on the northern Pacific coast of Canada. In SOL, we last raced on this route in 2012 and few people remember what happened there. Prepare your Riptide 50 well, it's going to be a lot of fun.

Newport Bermuda Race 2024

The 636-mile biennial Newport Bermuda Race is one of the oldest regularly scheduled ocean races, and with the Fastnet Race and the Sydney to Hobart Race, it is one of the three great classic races of the yachting world. Founded in 1906, this 53rd running of the Bermuda Race can again also be participated in online.
Entries are invited for one of the four divisions:
Double-Handed Division:
Jeanneau Sun Fast 3600
St. David's Lighthouse Division:
Santa Cruz 52
Gibbs Hill Lighthouse Division:
Judel Vrolijk 62
Finisterre Division:
Riptide 50
Details for each yacht are available in the ‘Particulars’ links below. As in real life, you can only sail one boat in one division, so choose your virtual yacht carefully, and because of the unusual (for SOL) 4-division nature of the event, please note results will not count towards any Sailonline rankings.
