[Haskell-cafe] Re: Computer time, independent of date

benchpress also uses System.CPUTime -- is that what you are looking for?

I'm writing a program that will read medical signs from many patients. It's important to have a precise measure of the time interval between some signs, and that can't depend on adjustments of time. (Supose my software is running midnight at the end of a year with leap seconds. I would get wrong time intervals.) System.CPUTime.getCPUTime is supposed to give cpu time my program have used. However, something like a platform independent way to know for how long the computer has been turned on would do all I need. Or, maybe, how much has elapsed since the program started. Thanks, Maurício
