One thing I've just noticed is that there is also a 'now' line on the timeline - a red vertical bar across the entire timeline. On the old 'date' versions, it was following the current system time and hence wandering forwards at one second per second. On this version, it is out of position and advancing at one millisecond per second. Presumably because you are scaling the axes by a factor of one thousand in order to gain the necessary precision in the plot. Something of a curiosity but certainly not a problem!

A moving red line? I never saw that! In any browser?


You have to zoom out a long way to see it. The trace files are time stamped from system boot, so fairly low numbers of seconds. The 'now' line is referenced from 1/1/1970 or whenever (albeit in milliseconds rather than seconds now). So is massively far into the future compared to any of the log data.
