I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ... What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere. As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon. Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way... As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number... svn path=/trunk/; revision=15520
