I need to do some accurate time measurements and I need to have access to a affordable / cheap and somewhat more reliable timestamp/time source than what is built in Windows/CPU.
I need to read the timestamp values from Windows.
Can anyone give some hints on what to use to get a better timestamp?
I guess some kind of PCI-Express based hardware timer card?
I don't need super-high accuracy, but a resolution around 100ns would be good.
