2015-03-08 08:00:46 - Premature Daylight Savings Time Discrepancy
For The Record:

It was noted during the San Sebastian-La Rochelle race that the time as given by the Slider portion of the Client Dashboard was 1 hour in advance of the UTC Box at the bottom of the screen. This affected only USA flagged skippers. I cannot state with certainty what the actual cause is for this anomaly however there appears to be an interaction between Wx info & the local CPU time/date functions. This occurred approximately 6 hours prior to when the clocks in the eastern time zone would have been moved forward for the start of DST but similarly included the west coast time zone as first reported by javakeda which was, in effect, 9 hours from their DST initiation. In trying to investigate the situation by varying the settings of the Time/Date control panel it was not possible to manually enter a value that would fall between 2-3 AM as if this hour is vacant & in order for this absence to cause the error as observed that the time calculation must be counting backwards from some internal reference point.

Carib Rum Run 2026


Ahoy, ye landlubbers and seasoned salts! Welcome back to Sailonline’s legendary Carib Rum Run, perfectly timed to kick off on International Talk Like a Pirate Day, 19 September!

This year, we command the magnificent Falkun—the ultimate high-tech superyacht modeled after the iconic Maltese Falcon. This 1759nm slalom takes us through the Caribbean’s rum islands to plunder barrels from local distilleries and deliver them to the rum-parched sands of Cancun.

Join SYC before the finish to disguise yer boat with a pirate name for this race only. Hoist the sails, sharpen yer cutlasses, and plot your winning course!
