Is it possible to set in advance a start/stop time for the X6 to record altitude/pressure data which can then be downloaded?
For example supposing I board an aeroplane tomorrow can I set the watch to record the information for 12 hours and retain that information for later download which may not be until a month later?

	Suunto X6 - Click for more info Just when you thought a sports watch couldn't get any better, Suunto introduces the X6 HR, X6 HRM and X6-HRT. These are truly the next generation in sports watches, packed with all of the technology that Suunto enthusiasts have been craving. Designed for Cross Sports applications, the X6 writstops are functionally very similar to the Suunto X6 - but with the added benefits of a heart rate monitor.
