In fact I am interested mainly in the time *difference* between successive measured data points. So if I could get a fix at the first measure to a complete time stamp, then all following need only a fairly accurate *relative* time from the first. I wonder if GetTickCount will get me a better value to milliseconds than Now()? I have heard of a "multimedia" time on Windows, which is more accurate, but I am not sure how to use it and if it exists on Linux... -- Bo Berglund Developer in Sweden -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
